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 + 8b = -6b + x + 4 for b in terms of x.
| -1\(\frac{2}{5}\)x + \(\frac{4}{5}\) | |
| -x - 1\(\frac{1}{5}\) | |
| -1\(\frac{4}{5}\)x + \(\frac{1}{5}\) | |
| -\(\frac{1}{3}\)x + \(\frac{7}{12}\) |
