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 5a + 6a = 2a + 9x - 6 for a in terms of x.
| 12x + 7 | |
| \(\frac{5}{8}\)x + \(\frac{7}{8}\) | |
| \(\frac{1}{7}\)x + \(\frac{1}{7}\) | |
| x - 2 |
