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 3a + 7a = -9a - 8x + 3 for a in terms of x.
| -1\(\frac{1}{4}\)x + \(\frac{1}{4}\) | |
| -\(\frac{3}{4}\)x + \(\frac{7}{12}\) | |
| -1\(\frac{4}{11}\)x - \(\frac{9}{11}\) | |
| -\(\frac{1}{2}\)x + \(\frac{5}{14}\) |
