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 7c - 2c = 6c + 3z - 2 for c in terms of z.
| 5z - 2 | |
| z - 2\(\frac{1}{4}\) | |
| -2\(\frac{2}{5}\)z + 1\(\frac{4}{5}\) | |
| 14z - 9 |
