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 -9b - 5b = 9b + 7x + 4 for b in terms of x.
| -\(\frac{2}{3}\)x - \(\frac{2}{9}\) | |
| -\(\frac{8}{15}\)x - \(\frac{1}{3}\) | |
| -\(\frac{6}{13}\)x + \(\frac{9}{13}\) | |
| \(\frac{5}{14}\)x - \(\frac{2}{7}\) |
