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 - c = -2c - 8z - 4 for c in terms of z.
| \(\frac{1}{2}\)z + \(\frac{2}{3}\) | |
| 9z - 1 | |
| 2\(\frac{1}{3}\)z + 1\(\frac{1}{3}\) | |
| 1\(\frac{2}{3}\)z + 1 |
