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 9c - 9c = -4c - 3z - 5 for c in terms of z.
| 3z + 4\(\frac{1}{2}\) | |
| z - 1 | |
| \(\frac{6}{13}\)z - \(\frac{5}{13}\) | |
| z - 4 |
