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 9b - 4b = -5b + 7x + 7 for b in terms of x.
| \(\frac{1}{2}\)x - \(\frac{1}{6}\) | |
| \(\frac{5}{7}\)x - \(\frac{2}{7}\) | |
| \(\frac{3}{8}\)x - \(\frac{7}{8}\) | |
| \(\frac{11}{14}\)x + \(\frac{1}{2}\) |
