Make use of the fact that side lengths in similar triangles are proportional.
.. 30/18 = (20 +x)/20
.. 20*(30/18) -20 = x . . . . multiply by 20, subtract 20
.. 33 1/3 -20 = x . . . . . . . . evaluate the product
.. 13 1/3 = x
2(x-y) - 3(x-2y) = 0
2(x) - 2(y) -3(x) -3(-2y) = 0
2x - 2y - 3x + 6y = 0
-x + 4y = 0
Value of x:
-x = -4y
-x / -1 = -4y / -1
x = 4y
Value of y:
-x + 4y = 0
4y = x
4y / 4 = x / 4
y = x/4
