Answer:
C (Bottom left)
Step-by-step explanation:
2x and 4x are like terms, because they both have a coefficient of "x".
2x-4x = -2x, so c is the right answer (or bottom right)
The correct answer is x + 7 = -2x + 5
This is because you combine the like terms, 2x and -4x, which is equal to -2x.
8x - 36
Use distributive property: a(b + c) = a*b + a*c
4(2x - 9)= 4*2x - 4*9
= 8x - 36
