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