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 -9c + 9c = -4c + 7z + 2 for c in terms of z.
| \(\frac{2}{5}\)z - \(\frac{2}{5}\) | |
| 1\(\frac{3}{11}\)z + \(\frac{6}{11}\) | |
| -5z - 7 | |
| 4\(\frac{1}{3}\)z - 3 |
