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 7a + 2a = -3a + 5x + 6 for a in terms of x.
| -\(\frac{1}{14}\)x - \(\frac{9}{14}\) | |
| -\(\frac{5}{17}\)x - \(\frac{1}{17}\) | |
| x - 6 | |
| \(\frac{3}{10}\)x + \(\frac{3}{5}\) |
