Answer: a) 10x-6x and c) 12x+2x-10x

Step-by-step explanation:

Lets start by simplifying all the expressions

a) 10x-6x=4x

b)7x+3x=10x

c)12x+2x-10x=14x-10x=4x

d)x-x+2x=2x

As you can see a and c both simplify to 4x meaning that is our answer.

Answer:

Options A and C

Solution:

  • In order to simplify these expressions, we should combine like terms:
  • 10x-6x=4x
  • 7x+3x=10x
  • 12x+2x-10x=14x-10x=4x (so expressions A & C are equivalent)
  • x-x+2x=0x+2x=2x
