### 2nd - Solve by substitution 2x - 2y 12 1x 5y 34?

2x - 2y = 12 (1)
1x + 5y = 34 (2)
x + 5y = 34 subtract 5y to both sides
x = 34 - 5y (3)
Substitute 34 - 5y for x into the first equation
2x - 2y = 12
2(34 - 5y) - 2y = 12
68 - 10y - 2y = 12
68 - 12y = 12 subtract 68 to both sides
-12y = -56 divide by -12 to both sides
y = 4.666666667
Substitute 4.7 for y into the third equation
x = 34 - 5y
x = 34 - 5(4.7)
x = 34 - 23.33333333
x = 10.66666667
