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 - 3b = 2b - 7x - 3 for b in terms of x.
| -4x - 3 | |
| -x + 9 | |
| -1\(\frac{1}{5}\)x - 1\(\frac{2}{5}\) | |
| -\(\frac{1}{2}\)x - \(\frac{3}{4}\) |
