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 -b - 9b = -2b - 4x - 7 for b in terms of x.
| -\(\frac{1}{2}\)x + \(\frac{1}{2}\) | |
| 5x - 7 | |
| \(\frac{1}{6}\)x - 1\(\frac{1}{3}\) | |
| \(\frac{7}{18}\)x - \(\frac{4}{9}\) |
