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 -6c + 3c = 4c - 2x + 7 for c in terms of x.
| \(\frac{1}{2}\)x - \(\frac{7}{10}\) | |
| 2\(\frac{1}{2}\)x - 3 | |
| -\(\frac{2}{5}\)x + 1\(\frac{4}{5}\) | |
| -x + \(\frac{8}{13}\) |
