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 + b = -7b - 7x + 9 for b in terms of x.
| -\(\frac{2}{5}\)x + \(\frac{3}{10}\) | |
| \(\frac{7}{8}\)x - \(\frac{3}{4}\) | |
| \(\frac{1}{6}\)x - \(\frac{5}{6}\) | |
| -1\(\frac{1}{3}\)x + 1\(\frac{1}{2}\) |
