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 - 8b = -b - 9x + 9 for b in terms of x.
| 13x + 4 | |
| x + 1\(\frac{1}{6}\) | |
| \(\frac{1}{8}\)x - 1\(\frac{1}{8}\) | |
| \(\frac{4}{15}\)x + \(\frac{3}{5}\) |
