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 + b = -9b - 2x + 7 for b in terms of x.
| -\(\frac{1}{4}\)x + \(\frac{7}{12}\) | |
| 5x - 9 | |
| 1\(\frac{1}{10}\)x - \(\frac{2}{5}\) | |
| 1\(\frac{4}{7}\)x + \(\frac{1}{7}\) |
