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 - 2c = 5c - 9z + 5 for c in terms of z.
| 10z - 7 | |
| 3z + 2\(\frac{1}{2}\) | |
| 1\(\frac{1}{6}\)z - \(\frac{5}{6}\) | |
| -4z + 1 |
