Algebra ProblemPan Balance Problem5(-3x – 2) – (x – 3) = -4(4x + 5) + 13
4First you distribute the 5 to (-3x – 2).The problem will look like this after distributing the 5.-15x – 10 – (x – 3) = -4(4x + 5) + 13
4Next you distribute the -4 to (4x + 5).The problem looks like this after this step.(-15x – 10) – (x – 3) = (-16x - 20 + 13)
4Then you add the -20 and 13 together.(-15x – 10) – (x – 3) = (-16x -7)
4Next you multiply the 4 on both sides of the problem.
Algebra Problem Continued…
The problem should look like this after multiplying the 4 on both sides of the Problem.
-15x – 10 – (x – 3) = -54x – 28
Then you can add x – 3 to -15x – 10. The problem should look like this when you are done.-16x – 7 = -54x - 28After that you can add 7 to both sides of the problem to keep it balanced.Your answer should be…-16x = -54x - 21
Next you add 54x to both sides of the problem.You should come to …38x = -21
Lastly, divide by 38 to solve for x. x = -21/38
IXLIXL is a math website that allows you to
practice your skills. For example, you could practice algebra, or probabilities, and even multiplication. The computer has awards that you can earn, and can tell you how long you have been practicing during the week, month or year. It keeps track of what skills you have practiced, and puts the data into a pie graph.
