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 + 4a = 6a - 8x + 4 for a in terms of x.
| 12x + 5 | |
| -\(\frac{1}{2}\)x - \(\frac{3}{5}\) | |
| 1\(\frac{1}{2}\)x - \(\frac{1}{2}\) | |
| \(\frac{1}{4}\)x + \(\frac{1}{3}\) |
