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 + 3a = 5a + 8x + 2 for a in terms of x.
| \(\frac{8}{11}\)x - \(\frac{4}{11}\) | |
| \(\frac{2}{5}\)x + 1 | |
| 1\(\frac{1}{4}\)x + \(\frac{1}{2}\) | |
| 2\(\frac{1}{3}\)x - 1\(\frac{2}{3}\) |
