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■

The equation is xy = 5*9 = 45 Alternatively, y = 45/x
y=2x+4 --> x=2y+4 ==> y=(x-4)/2
