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 - a = 8a - 8y - 5 for a in terms of y.
| -2\(\frac{1}{6}\)y + \(\frac{1}{6}\) | |
| -1\(\frac{1}{4}\)y - 1 | |
| 5y + 4 | |
| \(\frac{7}{12}\)y + \(\frac{5}{12}\) |
