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