Answer:

x = 5

Step-by-step explanation:

Equating the terms :

  • x + 3 = 2x - 2

Add 2 on both sides :

  • x + 3 + 2 = 2x - 2 + 2
  • x + 5 = 2x

Subtract x from both sides :

  • x + 5 - x = 2x - x
  • x = 5

Let's see

  • y=x+3
  • y=2x-2

Make them equal and solve for x

  • x+3=2x-2
  • -x=-5
  • x=5
