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 - 7b = 6b - 6x - 9 for b in terms of x.
| \(\frac{7}{8}\)x + \(\frac{7}{8}\) | |
| -\(\frac{1}{3}\)x + \(\frac{3}{5}\) | |
| -1\(\frac{3}{10}\)x - \(\frac{4}{5}\) | |
| \(\frac{1}{3}\)x - 3 |
