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 6b - 9b = -9b + 5x + 7 for b in terms of x.
| \(\frac{1}{15}\)x + \(\frac{1}{15}\) | |
| \(\frac{6}{17}\)x + \(\frac{9}{17}\) | |
| \(\frac{14}{15}\)x + \(\frac{7}{15}\) | |
| -\(\frac{13}{14}\)x + \(\frac{4}{7}\) |
