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 + 8a = a - 2x + 8 for a in terms of x.
| \(\frac{2}{9}\)x - \(\frac{5}{9}\) | |
| -\(\frac{5}{6}\)x + \(\frac{2}{3}\) | |
| -\(\frac{7}{9}\)x + \(\frac{7}{18}\) | |
| -10x + 8 |
