So just as promised, we’ve now solved for the absolute value of x plus 7, but we really need to solve for x. So how can alggebra reason through this? But the way to think about this is if you could solve for the ansewrs value expression, you could then– it then turns into a much simpler problem, then you can take it from there.

We’re just going to solve for the absolute value of x plus 7. Search Pre-Algebra All courses. How to graph functions and linear equations. You have these absolute values in it. So that’s going to be 14 absolute values of x plus 7, 14 times the absolute value of x plus 7.

So you could almost treat this expression– the absolute value of x plus 7, you can just treat it as a variable, and then once you solve for that, it becomes a simpler absolute value problem.

Algebra 2 Quadratic functions and inequalities Overview How to graph quadratic functions How to solve quadratic equations The Quadratic formula Standard deviation and normal distribution. And so what does this get us? The negative 6 and the answees x plus 7’s cancel out, or answer values of x plus 7’s cancel out, and that was intentional.


To log in and use all the features of Khan Academy, please enable JavaScript in your browser. So this is 8 times the absolute value of x plus 7 plus in that same color– is equal to negative 6 times the absolute value of x plus 7 plus 6.

So that’s how we got this. Algebra 2 How to graph functions and linear equations Overview Functions and linear equations Graph functions and relations Graph inequalities. Polynomials and radical expressions. Algebra 2 How to solve system of linear equations Overview Solving systems of equations in two variables Solving systems of equations in three variables.

So let’s try to do that. Algebra 2 Conic Sections Overview Distance between two points and the midpoint Equations of conic sections. Algebra 2 Discrete mathematics and probability Overview Counting principle Permutations and combinations Probabilities.

And I want to get all of these constant terms on to the right-hand side. Algebra 2 Equations and inequalities Overview Solve equations and simplify expressions Line plots and stem-and-leaf plots Absolute value Solve inequalities. Let’s try to solve for not x first.

So I want to get rid of this positive 4. If these two things are equal and we are being told that they are, then if you add something on this side, the only way that the equality will hold is if you still do it on the left-hand side. So that’s going to be equal to 2. Mathplanet hopes that you will enjoy studying Algebra answeds online with us!


Worked example: absolute value equation with two solutions

Quadratic functions and inequalities. So that’s one possibility for x. How to solve system of linear equations. Algebra 2 is the third math course in high school and will guide you through among other things linear equations, inequalities, graphs, matrices, polynomials and radical expressions, quadratic equations, functions, exponential and logarithmic expressions, sequences and series, probability and trigonometry.

This Algebra 2 math course is divided into 13 chapters and each chapter is divided into several lessons. Video transcript We’re asked to solve for x.

Let me just rewrite this equation so that the absolute values really pop out. Algebra 2 Sequences and series Overview Arithmetic answeers and series Geometric sequences and series Binomial theorem. Algebra 2 Rational expressions Overview Variation Operate on rational expressions. Algebra 2 Exponential and logarithmic functions Overview Exponential functions Logarithm and logarithm functions Logarithm property.

Solve absolute value equations. We can’t, of course, only do that to the right-hand side. Easiest way is to subtract 4 right over there, but if we do it on the left-hand side, we have to do it on the right-hand side as well.
