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