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