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 = 6c - 4x - 9 for c in terms of x.
| \(\frac{6}{13}\)x - \(\frac{7}{13}\) | |
| 1\(\frac{1}{10}\)x + \(\frac{9}{10}\) | |
| -x - \(\frac{1}{6}\) | |
| 5\(\frac{1}{2}\)x - 1\(\frac{1}{2}\) |
