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 2b + 8b = b - y - 4 for b in terms of y.
| -9y - 4 | |
| y + \(\frac{5}{11}\) | |
| -\(\frac{5}{6}\)y + 1\(\frac{1}{6}\) | |
| 3\(\frac{2}{5}\)y + 1\(\frac{1}{5}\) |
