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 - 9a = 3a + 7x - 7 for a in terms of x.
| -\(\frac{2}{13}\)x + \(\frac{6}{13}\) | |
| \(\frac{2}{3}\)x + 1\(\frac{2}{3}\) | |
| 8x - 3\(\frac{1}{2}\) | |
| -\(\frac{3}{13}\)x + \(\frac{2}{13}\) |
