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 b + 9b = -4b + 3x + 4 for b in terms of x.
| -x - 4 | |
| -1\(\frac{1}{5}\)x + \(\frac{4}{5}\) | |
| -\(\frac{6}{11}\)x - \(\frac{1}{11}\) | |
| -x - \(\frac{2}{5}\) |
