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