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 9b + b = -b - 8x - 7 for b in terms of x.
| 2\(\frac{1}{5}\)x + 1 | |
| -\(\frac{9}{10}\)x - \(\frac{7}{10}\) | |
| -1\(\frac{1}{8}\)x + \(\frac{1}{4}\) | |
| \(\frac{11}{13}\)x - \(\frac{6}{13}\) |
