1%2F8x - 10%2F7x = -73%2F32
Find the common denominator for the x's; that would be 56
7%2F56x - 80%2F56x = -73%2F32
combine like terms
-73%2F56x = -73%2F32
multiply both sides by -1
73%2F56x = 73%2F32
divide both sides by 73
1%2F56x = 1%2F32
or
x%2F56 = 1%2F32
cross multiply
32x = 56
x = 56%2F32 reduces to: 7%2F4
