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 2b + 7b = -8b + 9x - 7 for b in terms of x.
| \(\frac{1}{5}\)x - \(\frac{7}{10}\) | |
| 4x + \(\frac{2}{3}\) | |
| -2\(\frac{2}{3}\)x - 1\(\frac{2}{3}\) | |
| \(\frac{9}{14}\)x - \(\frac{4}{7}\) |
