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