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 3a - 2a = 6a + 9x - 2 for a in terms of x.
| -\(\frac{1}{3}\)x + \(\frac{4}{15}\) | |
| -3\(\frac{2}{3}\)x + \(\frac{2}{3}\) | |
| -\(\frac{7}{13}\)x - \(\frac{8}{13}\) | |
| x - 4\(\frac{1}{2}\) |
