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 8c + 2c = 2c - x - 1 for c in terms of x.
| -\(\frac{7}{12}\)x - \(\frac{5}{12}\) | |
| -\(\frac{1}{2}\)x - \(\frac{1}{6}\) | |
| 3\(\frac{3}{4}\)x + 2 | |
| -3x + 2 |
