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 -4b + 7b = 2b - x - 9 for b in terms of x.
| 1\(\frac{1}{3}\)x + 1\(\frac{1}{2}\) | |
| \(\frac{6}{7}\)x - \(\frac{1}{14}\) | |
| \(\frac{1}{2}\)x + \(\frac{1}{2}\) | |
| \(\frac{7}{11}\)x - \(\frac{9}{11}\) |
