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