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