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 - 5b = 7b - 4x + 4 for b in terms of x.
| -\(\frac{1}{8}\)x - \(\frac{1}{2}\) | |
| \(\frac{5}{12}\)x - \(\frac{1}{12}\) | |
| -1\(\frac{4}{9}\)x - \(\frac{7}{9}\) | |
| -x - 2\(\frac{2}{3}\) |
