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