x = 2.15 and y = 3.75
3y - 3 = 2y + 5 3y - 2y = 5 + 3 y = 8
x=4 y=0
x-y = 6 -x-3y = 22 -4y = 28 y = -7 So by substituting: x = -1 and y = -7
4x+3y = 6 3y = -4x+6 y = -4/3x+2 in slope intercept form
x = 2.15 and y = 3.75
(3y + 5)(y - 2)
5y+14+y = 3y-7 5y+y-3y = -7-14 3y = -21 y = -7
How do you add 2x plus 3y equals 18 in 5x-y equals 11
3y+5=y-25 2y=-30 y= -15
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
x = 3 and y = 0
2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6
y = 8
y=8
y=8
y=4
