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 -4b + 5b = -2b - 3x - 4 for b in terms of x.
| -\(\frac{3}{10}\)x - \(\frac{7}{10}\) | |
| 5x - 7 | |
| 1\(\frac{3}{14}\)x - \(\frac{4}{7}\) | |
| 4x + 2 |
