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 -5b - 2b = 8b - 3y - 9 for b in terms of y.
| -3y - 2 | |
| y - 2\(\frac{1}{3}\) | |
| \(\frac{1}{13}\)y + \(\frac{9}{13}\) | |
| -1\(\frac{5}{9}\)y - 1 |
