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 - c = 3c + 6z - 2 for c in terms of z.
| -\(\frac{7}{11}\)z + \(\frac{2}{11}\) | |
| -1\(\frac{5}{7}\)z - \(\frac{1}{7}\) | |
| 1\(\frac{4}{5}\)z - 1 | |
| \(\frac{2}{17}\)z - \(\frac{3}{17}\) |
