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