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 9a - 6a = 3a + 4x + 4 for a in terms of x.
| \(\frac{9}{10}\)x - \(\frac{1}{5}\) | |
| \(\frac{1}{7}\)x - \(\frac{3}{14}\) | |
| 1\(\frac{2}{3}\)x + \(\frac{2}{3}\) | |
| -\(\frac{1}{3}\)x - 2\(\frac{2}{3}\) |
