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 8a + 9a = 2a - 4x - 7 for a in terms of x.
| \(\frac{1}{10}\)x + \(\frac{3}{5}\) | |
| -\(\frac{3}{17}\)x + \(\frac{1}{17}\) | |
| 5\(\frac{2}{3}\)x + \(\frac{1}{3}\) | |
| -2\(\frac{1}{6}\)x - 1\(\frac{1}{6}\) |
