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