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 -2b + 9b = -3b - 2y - 1 for b in terms of y.
| -11y - 1 | |
| \(\frac{7}{10}\)y + \(\frac{1}{10}\) | |
| \(\frac{1}{8}\)y - \(\frac{1}{4}\) | |
| 2y - \(\frac{1}{2}\) |
