Solving OneStep Equations with Addition and Subtraction — Examples Expii
x + a − a = x. x + a − a = x. The inverse of subtraction is addition. If we start with a number x and subtract a number a, then adding a to the result will return us to the original number x. In symbols, x − a + a = x. x − a + a = x. Example 5. Solve x − 8 = 10 x − 8 = 10 for x.
