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 - 7b = -5b + 8x - 2 for b in terms of x.
| \(\frac{2}{7}\)x - \(\frac{2}{7}\) | |
| -1\(\frac{2}{13}\)x - \(\frac{1}{13}\) | |
| -4\(\frac{1}{2}\)x - 3\(\frac{1}{2}\) | |
| 1\(\frac{1}{14}\)x - \(\frac{1}{7}\) |
