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 + 6c = 9c - 5z - 4 for c in terms of z.
| \(\frac{3}{4}\)z + \(\frac{2}{3}\) | |
| -\(\frac{2}{3}\)z - \(\frac{1}{6}\) | |
| -\(\frac{1}{5}\)z + 1 | |
| \(\frac{11}{18}\)z + \(\frac{2}{9}\) |
