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