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 2c - 2c = 7c + 3x - 7 for c in terms of x.
| -x + 1\(\frac{2}{5}\) | |
| 1\(\frac{1}{6}\)x - \(\frac{1}{12}\) | |
| -3\(\frac{1}{2}\)x + 4 | |
| 5x - 1\(\frac{1}{2}\) |
