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 + 9b = -2b - 2x + 9 for b in terms of x.
| \(\frac{5}{8}\)x - \(\frac{7}{8}\) | |
| 1\(\frac{1}{7}\)x + \(\frac{4}{7}\) | |
| -1\(\frac{2}{9}\)x + 1 | |
| -\(\frac{6}{17}\)x - \(\frac{9}{17}\) |
