3x+2y=6 2y=-3x+6 y=-1.5x+3
3x-2y=6 -2y=-3x+6 y=1.5x-3
3x + 2y = 7
3x-2y = 5 -2y = -3x+5 y = 1.5x-2.5 in slope intercept form
y=16 x= -4
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
3x+2y=6 2y=-3x+6 y=-1.5x+3
2y-3x=4
3x-2y=6 -2y=-3x+6 y=1.5x-3
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
You cannot solve one linear equation in two unknown variables.
3x + 2y = 7
3x-2y = 5 -2y = -3x+5 y = 1.5x-2.5 in slope intercept form
y=16 x= -4
(2, -1)
4x-y=2, thereforey=4x-2sub y into 3x+2y=6...3x+8x-4=611x=10x=10/11
Standard form is: y = Mx + b so you must solve for y 3x = 2y + 7 3x - 7 = 2y 2y = 3x - 7 y = ( 3 / 2 )x - ( 7 / 2 )
