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 -9a - 3a = -5a + 9y + 5 for a in terms of y.
| \(\frac{1}{2}\)y + 1\(\frac{1}{3}\) | |
| -3y - 1\(\frac{1}{4}\) | |
| 3y - 1 | |
| -\(\frac{3}{4}\)y - \(\frac{5}{12}\) |
