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 -5b + 6b = -3b - 2x - 9 for b in terms of x.
| 4x + 4\(\frac{1}{2}\) | |
| -\(\frac{7}{15}\)x + \(\frac{2}{15}\) | |
| -\(\frac{4}{7}\)x + \(\frac{3}{7}\) | |
| -\(\frac{4}{13}\)x + \(\frac{6}{13}\) |
