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 7b - b = -9b - 3x - 7 for b in terms of x.
| -\(\frac{2}{5}\)x - \(\frac{3}{5}\) | |
| \(\frac{2}{11}\)x + \(\frac{6}{11}\) | |
| -\(\frac{1}{3}\)x - 2 | |
| -\(\frac{1}{8}\)x - \(\frac{7}{16}\) |
