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 + 9a = 3a - 5x + 8 for a in terms of x.
| -\(\frac{7}{12}\)x + \(\frac{2}{3}\) | |
| 3\(\frac{1}{2}\)x - 2 | |
| -4\(\frac{2}{3}\)x + 2\(\frac{2}{3}\) | |
| \(\frac{1}{3}\)x + 1 |
