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