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