Answer:

x=-5

Step-by-step explanation:

  1. Solve the bottom equation for y
  • You would just add 5x to both sides so that it cancels out leaving y = 5x + 34

    2. Put your new y equation into your top equation (4x + 2y = -2).  It should now be 4x + 2(5x + 34) = -2.

    3. Then, solve for x.

  • Distribute the 2 into 5x and 34. (Should now be 4x + 10x + 68 = -2).
  • Add the like terms - 4x and 10x. (Now 14x + 68 = -2).
  • Subtract 68 from both sides to get 14x on its own. (Now 14x = -70).
  • Divide both sides by positive 14 to get x on its own and the answer as to what x represents. (x = -5).

Hope that helps!
