2x - 2y = 12 (1)1x + 5y = 34 (2)x + 5y = 34 subtract 5y to both sidesx = 34 - 5y (3)Substitute 34 - 5y for x into the first equation2x - 2y = 122(34 - 5y) - 2y = 1268 - 10y - 2y = 1268 - 12y = 12 subtract 68 to both sides-12y = -56 divide by -12 to both sidesy = 4.666666667Substitute 4.7 for y into the third equationx = 34 - 5yx = 34 - 5(4.7)x = 34 - 23.33333333x = 10.66666667Check:
