a triangle has three sides. The second side is one more than double the first side and the third side is two less than the second side. The perimeter is 110. How long are the sides?
----------------------
Let the 1st side be "x".
Then 2nd side is "2x+1".
And 3rd side "2x+1-2" = 2x-1
----------------------
Equation:
x + 2x+1 + 2x-1 = 110
5x = 110
x = 22 (1st side)
2x+1 = 45 (2nd side)
2x-1 = 43 (3rd side)
