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 = 7a - 5y + 1 for a in terms of y.
| \(\frac{4}{7}\)y + \(\frac{3}{14}\) | |
| -\(\frac{1}{3}\)y - \(\frac{1}{12}\) | |
| y - 1\(\frac{1}{8}\) | |
| 5y + 5 |
