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 - 8b = -b - 8x - 9 for b in terms of x.
| x - 1\(\frac{2}{7}\) | |
| \(\frac{1}{3}\)x + 1\(\frac{1}{6}\) | |
| 1\(\frac{1}{12}\)x - \(\frac{2}{3}\) | |
| \(\frac{1}{2}\)x - 3\(\frac{1}{2}\) |
