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

First add coefficients: * 1x + 1x = 2x Second add the other values: * 4 + 5 = 9 Put it all together!: * 1x + 1x + 4 + 5 = 2x +9 * 2x + 9
