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 + 2a = -8a + 6x - 5 for a in terms of x.
| -\(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| -\(\frac{2}{17}\)x + \(\frac{9}{17}\) | |
| \(\frac{4}{13}\)x - \(\frac{5}{13}\) | |
| -7x - 2 |
