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