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 -2b + b = -8b - 9x + 7 for b in terms of x.
| -2x - 4 | |
| -1\(\frac{2}{3}\)x + 1\(\frac{1}{6}\) | |
| -\(\frac{9}{14}\)x - \(\frac{3}{14}\) | |
| -\(\frac{1}{2}\)x + \(\frac{1}{2}\) |
