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 = -9a - 3x + 3 for a in terms of x.
| -\(\frac{1}{6}\)x - 1\(\frac{1}{2}\) | |
| x - \(\frac{7}{10}\) | |
| -\(\frac{3}{8}\)x + \(\frac{7}{16}\) | |
| -\(\frac{12}{17}\)x + \(\frac{3}{17}\) |
