Question 1122066: I understand simple equations like " x + 8 = 6" and " x + 2 = 10".
x=-2 and x=8 because obviously 8+ 2 is 10. I just don't understand the steps it takes to do equations like 4 - 7x + 10 = 15 - 6x - 8
Please explain to me in detail the steps it takes to solve 4 - 7x + 10 = 15 - 6x - 8
Thank you

4 - 7x + 10 = 15 - 6x - 8
-----------
It's not much different.
You can make step 1, add 7x
-->
4 + 10 = 15 + x - 8 --- now there's only 1 x term
14 = x + 7
x = 7

4-7x%2B10=15-6x-8

Collect and simplify like terms, and finally undo what is done to variable x.

-7x%2B14=-6x%2B7
-7x%2B14-14%2B6x=-6x%2B7-14%2B6x
-7x%2B6x%2B0=0-7
-x=-7
highlight%28x=7%29

Understand that steps can vary.

check the solution:
4-7%2A7%2B10=15-6%2A7-8
4-49%2B10=15-42-8
-49%2B14=7-42
35=35solutionworks.
