-3x + 2y = 8 x + 4y = -4 x + 4y = -4 x = -4 - 4y Substitute, x = -4 - 4y in, -3x + 2y = 8 -3(-4 - 4y) + 2y = 8 12 + 12y + 2y = 8 14y = -4 y = -4/14 y = -2/7 Substitute, y = -2/7 in either equation to find x. Then check your solutions in the original equat...

Solve without graphing first so that you know what x and y equal. Then pick three points for each to graph. 3x + y = 6 x = 1, y = 3 x = 2, y = 0 x = 3, y = -3 2x + 3y = 13 x = 1, y = 11/3 = 3.67 (3.67 is a little more than 3 1/2) x = 2, y = 3 x = 3, y = 7...
