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