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