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

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)

This is Simultaneous equ'ns. 3x + 5y = -1 2x -5y = 16 Add the two eq'ns. This will eliminate 'y' Hence 5x = 15 x = 3 When x = 3 , substitute into either eq'n to yimnd 'y'. Hence 3)3) + 5y = -1 9 + 5y = -1 5y = -10 y = -10/5 = -2 So the solution in ( x,y) form is ( 3, -2).
-5y +2x = -10 -5y = -2x -10 y = 2/5x +2 So the slope = 2/5 and the y intercept = 2

If: 2x+5y = 2 and -3x-y = -3Then it works out that: x = 1 and y = 0
y=x+5
