x=-21
Check
-21+9=-12 = True

X + 9 = -12 equals x = -21.

First, subtract 9 from both sides. / Your problem should look like: x = -12 - 9.
Second, simplify -12 - 9 to get -21. / Your problem should look like: x = -21, which is your answer.

Write the equation of the inverse of y = x-6
erik [133]
Y = (x - 6)/4

to find the inverse of a function, you swap the x and y variables, then solve for y.
y = (x - 6)/4 ... swap x and y
x = (y - 6)/4 ... solve for y, start by multiplying both sides by 4 to cancel out your denominator
4x = (y - 6) ... add 6 to both sides
4x + 6 = y

your inverse function is y = 4x + 6
