You can put this solution on YOUR website!
A really good description of how to find an inverse function is given here --> http://www.purplemath.com/modules/invrsfcn3.htm
Given:y+=+3x+-2
y%2B2=+3x+
%28y%2B2%29%2F3+=+x+
Now swap the variable names to get the inverse
y+=+%28x%2B2%29%2F3
All we need to do now is start subbing in the values given.
x = 37 --> y = 13 == letter M
x = 25 --> y = 9 == letter I
x = 19 --> y = 7 == letter G
x = 61 --> y = 21 == letter U
x = 13 --> y = 5 == letter E
Keep at the rest
