A base of an isosceles triangle is 2x+y units and the legs of the triangle are 3x and 4y units. The perimeter of the triangle is 70 units. Find the values of x and y and determine the length of each side of the triangle.
***
base+2legs=perimeter
2x+y+3x+4y=70
3x=4y (legs of isosceles triangles are equal to each other)
y=3x/4

lcd=4
3x+32x=280
35x=280
x=8
y=3x/4=6
length of each side of the triangle=3x=4y=24 units
