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 -8a - 3a = 4a - 9y + 3 for a in terms of y.
| \(\frac{1}{2}\)y - \(\frac{1}{4}\) | |
| -\(\frac{3}{4}\)y + \(\frac{3}{8}\) | |
| 1\(\frac{3}{4}\)y + 1 | |
| -5\(\frac{1}{2}\)y - 3 |
