$x = 65$
#### Explanation:
$2 x + 2 = 3 x - 63$
Firstly, we can subtract $2 x$ from both sides of the equation:
$2 x + 2 - 2 x = 3 x - 63 - 2 x$
Which gives:
$2 = x - 63$
We can then add $63$ to both sides also:

# Math Help - Inverse help!
1. ## Inverse help!
If f= x+1/x+3 , find g, it's inverse, if it exists.
2. Finding the Inverse of a Function
This site gives a good explanation.
$y=\frac {x+1}{x+3}$
Solve for x:
$y(x+3)=x+1$
$
yx+3y=x+1$
$3y-1=x-yx$
$3y-1=x(1-y)$
$x=\frac {3y-1}{1-y}$
Now switch the x and y:
$y... |
