5x - x + 12 + 2x - 7 = 10
We're simply just trying to isolate x :)
However, we must first simplify the equation by adding like terms.
(5x - x + 2x) + (12 - 7) = 10
Simplify.
6x + 5 = 10
Then, we must subtract 5 from both sides.
6x = 10 - 5
Simplify.
6x = 5
Divide both sides by 6.
6x ÷ 6 = 5 ÷ 6
Simplify.
x = 5/6
B. x = 5/6
~Hope I helped!~
