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