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 9b + b = 8b + 7x - 6 for b in terms of x.
| -\(\frac{1}{2}\)x + \(\frac{1}{8}\) | |
| 1\(\frac{1}{3}\)x + \(\frac{2}{3}\) | |
| -\(\frac{1}{4}\)x - \(\frac{2}{3}\) | |
| 6x - 6 |
