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 5c - c = -c - 2z - 8 for c in terms of z.
| 2z - 6 | |
| -\(\frac{1}{6}\)z - 1\(\frac{1}{3}\) | |
| -1\(\frac{1}{11}\)z - \(\frac{4}{11}\) | |
| -1\(\frac{2}{7}\)z - \(\frac{3}{7}\) |
