Answer:

x = 2

y = 0

Explanation:

2x + y = 4

3x - y = 6

  • Add first and second equation up.
  1. 2x + y + 3x - y = 4 + 6
  2. 5x = 10
  • Notice how +y was eliminated by -y.

Divide both sides of the equation with 5:

x = 2

  • To find the value of y, replace x with 2 in the first equation.

2×2 + y = 4

4 + y = 4

  • Subtract 4 from both sides.

y = 0
