Step-by-step explanation:

2x+2y= -8

3x-2y= 33

first cancel out +2y&-2y

  • then chose 1 equation...let's take the first one and then 2x= -8
  • divided both sides by 2:x= -4
  • then substitute the value of x in the second equation:3(-4)-2y=33
  • -12-2y=33
  • 2y=33+12
  • 2y=45
  • divide both sides by 2: y=22.5
