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 - 5b = -2b - 8x - 4 for b in terms of x.
| 15x + 3 | |
| -\(\frac{7}{16}\)x + \(\frac{3}{8}\) | |
| -\(\frac{9}{11}\)x - \(\frac{1}{11}\) | |
| \(\frac{3}{7}\)x + \(\frac{4}{7}\) |
