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 4c + 7c = 5c - 4x + 9 for c in terms of x.
| x + \(\frac{3}{10}\) | |
| -2x - 1\(\frac{4}{5}\) | |
| -\(\frac{1}{6}\)x + \(\frac{7}{18}\) | |
| 11x - 9 |
