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 - 3b = 7b + x - 9 for b in terms of x.
| -\(\frac{2}{5}\)x + \(\frac{4}{5}\) | |
| -\(\frac{1}{11}\)x - \(\frac{8}{11}\) | |
| -\(\frac{4}{13}\)x + \(\frac{9}{13}\) | |
| -\(\frac{4}{9}\)x - \(\frac{7}{9}\) |
