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 -6b + b = -5b - 8x + 7 for b in terms of x.
| 9x - 7 | |
| -\(\frac{4}{7}\)x + \(\frac{2}{7}\) | |
| -1\(\frac{9}{10}\)x + \(\frac{1}{5}\) | |
| -9x - 1 |
