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