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