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