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 - 3b = 8b + 5y + 6 for b in terms of y.
| 10y + 9 | |
| \(\frac{1}{5}\)y - \(\frac{3}{5}\) | |
| -\(\frac{8}{9}\)y - \(\frac{2}{3}\) | |
| -2y + 4 |
