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 - 8c = -3c + 6z + 5 for c in terms of z.
| \(\frac{1}{13}\)z - \(\frac{4}{13}\) | |
| \(\frac{1}{5}\)z + \(\frac{3}{5}\) | |
| 7z + 2\(\frac{1}{2}\) | |
| -\(\frac{1}{2}\)z + \(\frac{1}{7}\) |
