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 8a - a = 5a + 2x + 8 for a in terms of x.
| x + 2\(\frac{2}{3}\) | |
| 3x + \(\frac{4}{5}\) | |
| -2\(\frac{1}{3}\)x + \(\frac{5}{6}\) | |
| -x + \(\frac{9}{11}\) |
