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 + 7c = -8c - 4x - 6 for c in terms of x.
| 2\(\frac{1}{4}\)x - 1\(\frac{1}{2}\) | |
| -\(\frac{1}{3}\)x + \(\frac{1}{3}\) | |
| -1\(\frac{2}{9}\)x - \(\frac{2}{3}\) | |
| -\(\frac{6}{17}\)x - \(\frac{6}{17}\) |
