:
x%2F%28%285x%2B10%29%29 + %28%28x-3%29%29%2F%28%28x%2B2%29%29 = 7%2F5
:
x%2F%285%28x%2B2%29%29 + %28%28x-3%29%29%2F%28%28x%2B2%29%29 = 7%2F5
:
Multiply equation by 5(x+2), gets rid of the denominators and you have:
x + 5(x-3) = 7(x+2)
:
x + 5x - 15 = 7x + 14
:
6x - 15 = 7x + 14
:
6x - 7x = 14 + 15
:
-1x = 29
x = 29/-1
x = -29
