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 5a - 6a = -2a + 7x - 7 for a in terms of x.
| -\(\frac{5}{14}\)x + \(\frac{2}{7}\) | |
| \(\frac{1}{4}\)x + \(\frac{1}{2}\) | |
| 3x - 3\(\frac{1}{2}\) | |
| 1\(\frac{6}{7}\)x - 1 |
