Question

What is the inverse of x-2

Answer 1

Answer:

y = x + 2

Step-by-step explanation:

The expression x-2 is from the equation y = x - 2.

To find the inverse of the equation, switch the "x" and "y" variables, then solve  or isolate for "y", meaning to separate it from the other numbers.

y = x - 2     Original equation

x = y - 2     Switched "x" and "y" variables

x + 2 = y - 2 + 2     Add 2 to both sides to cancel out '-2' on the side with "y"

x + 2 = y    

y = x + 2     Variable is on left side in standard formatting

To isolate, do the reverse operation for the number you want to get rid of.

On the side with "y", I wanted to get rid of '-2' so I could separate "y" from everything else. '+2' is the reverse operation for '-2'.
