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 -6b - b = -7b - x + 8 for b in terms of x.
| x + 8 | |
| -\(\frac{1}{4}\)x + \(\frac{2}{3}\) | |
| \(\frac{1}{4}\)x - \(\frac{3}{4}\) | |
| -\(\frac{1}{5}\)x - \(\frac{1}{5}\) |
