Question 278745: A triangular garden is a different length on each side. Side two is 3 meters shorter than side one, and side three is 8 meters longer than side one. If the perimeter of the garden is 65 meters, what is the length of each side?
Here is what I have so far:
a+b+c=65m
b=3-a
c=8+a
Solve for a:
a+3-a+8+a=65m

You can put this solution on YOUR website!
b=a-3 not 3-a
so
a+a-3+a+8=65
3a+5=65
3a=60
a=20
b=20-3
c=20+8
