8x + 5y = 22<br> -8x + y = 14
finlep [7]

Answer:

Y = 6 X=-1

Step-by-step explanation:

  1. Add the numbers 8x+-8x=0. 5y+y=6y. 22+14=36
  2. So that means 6y=36. So Y would equal 6
  3. Substitute the values it one of the original equations. 8x + 5(6) =22. 8x+30=22
  4. Minus 22 from both sides.
  5. That would give you 8x=-8
  6. So x would equal - 1
