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