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 4a - 8a = 3a + 5y + 4 for a in terms of y.
| -\(\frac{7}{12}\)y + \(\frac{1}{6}\) | |
| \(\frac{11}{14}\)y + \(\frac{4}{7}\) | |
| 13y + 4 | |
| -\(\frac{1}{8}\)y - \(\frac{7}{8}\) |
