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 + 8x - 4 for b in terms of x.
| x - 1 | |
| 2\(\frac{4}{5}\)x + \(\frac{1}{5}\) | |
| -\(\frac{4}{5}\)x + \(\frac{4}{5}\) | |
| 5\(\frac{1}{2}\)x - 4 |
