Question

Find an equation for the inverse of the following relation.

y=12x-3

Answer 1

Your answer would be y=x+3/12

Explanation:

Firstly, you'll switch sides of the equation.

y=12x+3 ---> x=12y-3

Next, add 3 to both sides.

x=12y-3 ---> 12y-3+3=x+3

Simplify it.

12y-3+3=x+3 ---> 12y=x+3

Then, divide both sides by 12.

12y=x+3 ---> 12y/12 = x/12 + 3/12

Simplify once more.

12y/12 = x/12 + 3/12 --- y= x+3/12

y=x+3/12 would be your answer.
