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 + 9a = 4a + x + 2 for a in terms of x.
| \(\frac{5}{9}\)x + \(\frac{7}{9}\) | |
| -11x - 7 | |
| -\(\frac{6}{7}\)x - \(\frac{6}{7}\) | |
| -1\(\frac{3}{5}\)x + \(\frac{2}{5}\) |
