Question 269327: Hi, I need some help with this word problem.
The perimeter of a triangle is 93 centimeters. If two sides are equally long and the third side in 9 centimeters longer than the others, find the lengths of the three sides.
So far this is what I get out of the word problem
a+b+c=93
Thanks for your help!

You can put this solution on YOUR website!
let one side be x
another side is also x
third side is 9 inch more than x
permimeter = x+x+x+9=93
3x+9=93
3x=93-9
3x=84
x=84/3
x=28
the sides are 28, 28, and 37
