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