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 = -5b - x - 9 for b in terms of x.
| x + \(\frac{1}{15}\) | |
| -1\(\frac{1}{2}\)x + 4\(\frac{1}{2}\) | |
| x - \(\frac{7}{11}\) | |
| 2x - 8 |
