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 -2a + 6a = 9a + 3x - 4 for a in terms of x.
| \(\frac{3}{11}\)x + \(\frac{4}{11}\) | |
| 3\(\frac{1}{2}\)x + 1\(\frac{1}{2}\) | |
| x - 1\(\frac{1}{5}\) | |
| -14x + 3 |
