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 + 9a = -a + 8y - 5 for a in terms of y.
| 1\(\frac{1}{5}\)y - \(\frac{1}{2}\) | |
| y + \(\frac{5}{14}\) | |
| -\(\frac{1}{10}\)y - \(\frac{1}{2}\) | |
| \(\frac{1}{3}\)y - \(\frac{4}{9}\) |
