When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 9a - 8a = 8a - 5y + 6 for a in terms of y.
| 3y + 6 | |
| 1\(\frac{1}{4}\)y - \(\frac{3}{4}\) | |
| -\(\frac{5}{12}\)y - \(\frac{1}{3}\) | |
| -8y + 3\(\frac{1}{2}\) |
