X is 6
4x24=96 20 x 4 = 80 4 x 4 = 16 80 + 16 = 96
x = 5 y = 2 4x - 3y = ? 4(5) - 3(2) = ? 20 - 6 = 14
The inverse of an equation is rewriting it as a function of the other variable. Simply solve the equation for x instead of y. y=9x can be written as x= (1/9)y --> fy=y/9◄ y=4x+6 (or 4x+6=y) -> 4x=y-6 -> x=(y-6)/4 --> gy=(y-6)/4■
4x - 7 = -15 4x = -8 x = -2
