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