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 -6b - 3b = 9b - 3y - 8 for b in terms of y.
| 7\(\frac{1}{2}\)y - 1 | |
| y + \(\frac{8}{15}\) | |
| \(\frac{1}{7}\)y - \(\frac{4}{7}\) | |
| -\(\frac{2}{3}\)y + 1 |
