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 - 3c = 2c + 8z - 4 for c in terms of z.
| 6z + 5 | |
| -11z + 4 | |
| 5\(\frac{1}{2}\)z + 1\(\frac{1}{2}\) | |
| \(\frac{1}{5}\)z - \(\frac{7}{10}\) |
