6x plus 3y minus 2x plus 5y equals 4x plus 8y.
2x +n5y=12
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
It equals x+5y simplified
(4, -1)
2x-5y+15=0 -5y=-2x-15 y=(2/5)x+3
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
2x +n5y=12
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
It equals x+5y simplified
(4, -1)
3x + 5y = -1 2x - 5y = 16 Add the two equations: 5x = 15 or x = 3 Substitute for x in the first equation: 3*3 + 5y = -1 15 + 5y = -1 5y = -10 so y = -10/5 = -2 The solution is (x, y) = (3, -2)
-5y +2x = -10 -5y = -2x -10 y = 2/5x +2 So the slope = 2/5 and the y intercept = 2

(2, 3)
0 = -2x + 5y - 15 -5y = -2x - 15 y = 2x/5 + 3
If: 2x+5y = 2 and -3x-y = -3Then it works out that: x = 1 and y = 0
