Answer:
10+2x=4x
-2x -2x
10=2x
10/2 2/2
5=x
Step-by-step explanation:
So when you simplify an expression with two or more variables you always go for the lowest variable first. Then you can do your normal inverse steps.
9(3+5)
if you go through each answer choice you will notice that none of the rest are right
8(3+6) = 24 +48
8(19 +37) = 152 + 296
9(18 +36)= 162 +324
