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 8b + 5b = 5b - 6y - 4 for b in terms of y.
| 3y - 1 | |
| -y - 1 | |
| -3\(\frac{2}{3}\)y - 1\(\frac{1}{3}\) | |
| \(\frac{2}{3}\)y - \(\frac{4}{15}\) |
