Solve the system by the addition method <br> 4x=3y-8<br> -16x+4y=32
butalik [34]
4x = 3y - 8
 4         4
  x = ³/₄y - 2

                  -16x + 4y = 32
       -16(³/₄y - 2) + 4y = 32
-16(³/₄y) + 16(2) + 4y = 32
          -12y + 32 + 4y = 32
          -12y + 4y + 32 = 32
                    -8y + 32 = 32
                           - 32  - 32
                            -8y = 0
                             -8    -8
                               y = 0
x = ³/₄y - 2
x = ³/₄(0) - 2
x = 0 - 2
x = -2

(x, y) = (-2, 0)
