Question 492511: A triangle has a perimeter of 30m. The length of the 2nd side is 5m more than the length of the 1st side. The third side is 3 meters less than twice the 1st side. How long is each side?
These always give me trouble!
My solution came out with two negative answers so I know they cannot be right. How would I set up the equation?
Here is what I have:
P=30m
2nd side=P+5m
3rd side=30m(2)-3m
30m=P+5m+30m(2)-3m
30m=P+5m+60m-3m
30m=P+62m
30m-62m=P+62m-62m
-32m=P
