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