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 -3b - 7b = 9b - 9y - 9 for b in terms of y.
| \(\frac{1}{6}\)y + \(\frac{3}{4}\) | |
| y + 2\(\frac{1}{2}\) | |
| -2\(\frac{2}{3}\)y + 1\(\frac{1}{2}\) | |
| -\(\frac{9}{10}\)y - \(\frac{1}{5}\) |
