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 - 9a = 9a - 3y + 1 for a in terms of y.
| -\(\frac{3}{7}\)y - \(\frac{1}{14}\) | |
| 5y + \(\frac{1}{2}\) | |
| 1\(\frac{1}{3}\)y + 3 | |
| y + \(\frac{1}{4}\) |
