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 -5a - 3a = -4a + 5y + 5 for a in terms of y.
| -y + 1 | |
| 2y + \(\frac{1}{2}\) | |
| 13y - 1 | |
| -8y - 5 |
