1. Get all the terms with the unknown (variable) on one side of the equation, and constants/integers/numbers on the other. For your equation, you only have to subtract 'x' from both sides of the equation.
5/8x + 1/16x - x = 5/16
2. Now, using the Distributive Property of expressions---you know, where ax + bx + cx = (a + b + c) * x, group the coefficients of x:
(5/8 + 1/16 - 1) * x = 5/16
3. Use your knowledge of summing fractions---you know, get the denominator where everything is the same denominator
(10/16 + 1/16 - 16/16) * x = 5/16
4. And do the summing:
-5/16 * x = 5/16
5. You now finish by solving for x, which means multiplying by -16/5 on both sides of the equation:
x = -16/5 * 5/16 = -1
and you have your answer
