when y = 3, 8y-4y = 4y = 4*3 = 12
assuming that the question is asking 4y = 48, y = 12
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
3x=4y-x 4x=4y x=y
4y-9 = 15 4y = 15+9 4y = 24 y = 6
-y + -4y = -5y
4y = 929 4y/4 = 929/4 y = 232.25

4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
when y = 3, 8y-4y = 4y = 4*3 = 12
4y+y=10 5y=10 y=2
assuming that the question is asking 4y = 48, y = 12
x2 -y2 +4y-4=(x+y)(x-y)+4y-4
4 - 3y - y = 04 - 4y = 0add 4y to both sides4 = 4ydivide both sides by 4y = 1
4y - 5 = 7x ∴y = 7/4x + 5/4 slope = 7/4, or 1.75 4y - 5 = 7x ∴4y/7 - 5/7 = x ∴4y/7 - 5/7 = 0 ∴4y = 5 ∴y = 1.2 the y-intercept is 1.2
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
