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 - 9b = -4b - 8x + 2 for b in terms of x.
| 1\(\frac{1}{14}\)x + \(\frac{2}{7}\) | |
| -1\(\frac{1}{10}\)x - \(\frac{4}{5}\) | |
| x - \(\frac{2}{3}\) | |
| \(\frac{1}{7}\)x + \(\frac{2}{7}\) |
