Her next step would be to add 12 to both sides of the equation
Step-by-step explanation:
Which would make the equation 4x=28
Then you divide both sides by 4 giving you x=7
Answer:
see explanation
Step-by-step explanation:
let y = f(x), then
y = 11x - 1
Interchange x and y and solve for y
x = 11y - 1 ( add 1 to both sides )
x + 1 = 11y ( divide both sides by 11 )
y =
, hence
(x) =
