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 4b - 5b = 7b + 4x + 9 for b in terms of x.
| 1\(\frac{1}{11}\)x - \(\frac{1}{11}\) | |
| -\(\frac{1}{2}\)x - \(\frac{7}{10}\) | |
| \(\frac{6}{11}\)x - \(\frac{4}{11}\) | |
| -3x - 3 |
