oh ok
what do you get when you add like terms?
OpenStudy (anonymous):
What do you mean
OpenStudy (welshfella):
well you have like terms -6 + 7x on left and -15 + 28 on the right
they can be simplified
OpenStudy (welshfella):
* -6x + 7x on the left

Simplifying
32 + -6x + 7x = -15 + 28
Combine like terms: -6x + 7x = 1x
32 + 1x = -15 + 28
Combine like terms: -15 + 28 = 13
32 + 1x = 13
Solving
32 + 1x = 13
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-32' to each side of the equation.
32 + -32 + 1x = 13 + -32
Combine like terms: 32 + -32 = 0
0 + 1x = 13 + -32
1x = 13 + -32
Combine like terms: 13 + -32 = -19
1x = -19
Divide each side by '1'.
x = -19
Simplifying
x = -19
