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 -8b - 5b = b + 7x + 9 for b in terms of x.
| -1\(\frac{1}{3}\)x - 1 | |
| \(\frac{3}{5}\)x - 1\(\frac{1}{5}\) | |
| 1\(\frac{1}{6}\)x - \(\frac{1}{2}\) | |
| 2x - 4 |
