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 = -2c - 3z + 6 for c in terms of z.
| z - \(\frac{5}{9}\) | |
| -1\(\frac{1}{11}\)z + \(\frac{6}{11}\) | |
| -\(\frac{5}{7}\)z - \(\frac{2}{7}\) | |
| \(\frac{5}{8}\)z - \(\frac{1}{4}\) |
