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