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