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 3a - a = 4a - 3y - 5 for a in terms of y.
| 2y + 5 | |
| -\(\frac{5}{12}\)y + \(\frac{7}{12}\) | |
| -11y - 6 | |
| -2\(\frac{2}{5}\)y - \(\frac{4}{5}\) |
