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 -6c - 2c = -9c - 5z - 4 for c in terms of z.
| -14z + 3 | |
| -z - 1\(\frac{1}{3}\) | |
| -\(\frac{1}{5}\)z + \(\frac{4}{5}\) | |
| \(\frac{5}{6}\)z + \(\frac{1}{6}\) |
