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