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 7b - 4b = -8b - x - 7 for b in terms of x.
| \(\frac{2}{5}\)x - \(\frac{1}{2}\) | |
| \(\frac{1}{5}\)x - \(\frac{7}{15}\) | |
| -\(\frac{1}{11}\)x - \(\frac{2}{11}\) | |
| -2x - \(\frac{2}{5}\) |
