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 -3b - b = 9b + 2x - 9 for b in terms of x.
| -\(\frac{1}{4}\)x + \(\frac{3}{4}\) | |
| -1\(\frac{2}{7}\)x - 1 | |
| -\(\frac{3}{13}\)x - \(\frac{7}{13}\) | |
| \(\frac{1}{5}\)x + \(\frac{9}{10}\) |
