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 + 9a = -5a - 8x + 2 for a in terms of x.
| \(\frac{2}{15}\)x - \(\frac{1}{3}\) | |
| -8\(\frac{1}{2}\)x + 1 | |
| 5\(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| 1\(\frac{1}{2}\)x - 4 |
