Find the solution of this system of equations.
separate the x- and y-values with a comma.
x= 5 + y
28x – 9y= -12

x= 5 + y
28x – 9y = -12

substitute x= 5 + y into 28x – 9y = -12

28x – 9y= -12
28(5 + y) – 9y = -12
140 + 28y - 9y = -12
19y = -152
    y = -8

x = 5 + y
x = 5 - 8
x = -3

solution (-3, -8)

The first one is 2/3the second is 1/160the third is 4/125
