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 + 3c = 9c - 8z - 3 for c in terms of z.
| \(\frac{10}{11}\)z - \(\frac{7}{11}\) | |
| \(\frac{1}{5}\)z + \(\frac{1}{5}\) | |
| -5\(\frac{2}{3}\)z - 1\(\frac{1}{3}\) | |
| \(\frac{11}{18}\)z + \(\frac{1}{6}\) |
