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 - 2x - 8 for c in terms of x.
| -\(\frac{6}{7}\)x + 1\(\frac{2}{7}\) | |
| 2x + 7 | |
| -\(\frac{5}{9}\)x + \(\frac{8}{9}\) | |
| -1\(\frac{2}{5}\)x + \(\frac{3}{10}\) |
