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