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 4c + c = -2c - 7z - 9 for c in terms of z.
| 1\(\frac{3}{8}\)z + 1\(\frac{1}{8}\) | |
| 1\(\frac{1}{12}\)z + \(\frac{1}{3}\) | |
| -1\(\frac{1}{3}\)z - 1\(\frac{1}{2}\) | |
| 12z - 1 |
