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