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