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