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 - 6a = -2a - 5y + 1 for a in terms of y.
| 7y - 1 | |
| \(\frac{1}{11}\)y + \(\frac{1}{11}\) | |
| -1\(\frac{1}{3}\)y + \(\frac{1}{9}\) | |
| \(\frac{5}{14}\)y - \(\frac{4}{7}\) |
