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 + 6x - 1 for b in terms of x.
| 6x - 4 | |
| \(\frac{4}{7}\)x - \(\frac{4}{7}\) | |
| 2x - 1 | |
| \(\frac{1}{2}\)x - \(\frac{3}{10}\) |
