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 -9b - b = 8b - 3y + 3 for b in terms of y.
| -1\(\frac{1}{4}\)y + \(\frac{3}{8}\) | |
| \(\frac{1}{3}\)y + \(\frac{4}{9}\) | |
| \(\frac{2}{17}\)y - \(\frac{3}{17}\) | |
| \(\frac{1}{3}\)y - \(\frac{1}{3}\) |
