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