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 6a - a = a - x - 3 for a in terms of x.
| -\(\frac{1}{2}\)x + 3 | |
| \(\frac{1}{4}\)x - \(\frac{2}{3}\) | |
| -8x + 1 | |
| x - \(\frac{3}{5}\) |
