Answer:

  • x=1
  • y= -2

Step-by-step explanation:

  • 3x-2y =7
  • x+2y= -3
  • 4x=4
  • x=4/4
  • x=1
  • 3x-2y=7
  • 3(1)-2y=7
  • 3-2y=7
  • -2y=7-3
  • -2y=4
  • 2y=-4
  • y=-4/2
  • y= -2
  • Verify solution
  • x+2y= -3
  • 1+2y= -3
  • 2y=-3-1
  • 2y= -4
  • y= -4/2
  • y= -2

Answer:

x = 1

y = -2

Step-by-step explanation:

adding both quation we get

3x -2y + x + 2y =7 + -3

4x = 4

x = 1

substituting this equation in the earlier equation we get

3 * 1 -2y = 7

3 - 2y = 7

-2y = 4

y = -2
