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 + 6a = -9a - 4x + 1 for a in terms of x.
| \(\frac{1}{4}\)x + \(\frac{7}{12}\) | |
| 2\(\frac{4}{5}\)x - 1\(\frac{1}{5}\) | |
| -\(\frac{5}{8}\)x + \(\frac{1}{16}\) | |
| \(\frac{1}{8}\)x + \(\frac{7}{8}\) |
