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 a - 8a = -4a + 9y - 5 for a in terms of y.
| -\(\frac{2}{3}\)y + 2 | |
| 3\(\frac{2}{5}\)y - 1 | |
| \(\frac{5}{14}\)y - \(\frac{2}{7}\) | |
| -2\(\frac{1}{6}\)y - \(\frac{2}{3}\) |
