Question 903989: The two equal sides of an isosceles triangle each have a length of 2x +3y - 1. the perimeter of the triangle is 7x + 9y. determine the length of the other side
I know the answer is 3x+3y+2, but I don't understand how I'm supposed to get there. Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! B the Other Side
P = (2x+3y-1) + (2x+3y-1) + B
Question States***
(2x+3y-1) + (2x+3y-1) + B = 7x + 9y
4x + 6y - 2 + B = 7x + 9y
B = 7x + 9y - 4x - 6y +2 = 3x + 3y + 2
