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 - 4c = -4c + 6z + 3 for c in terms of z.
| -\(\frac{1}{3}\)z + \(\frac{1}{2}\) | |
| -\(\frac{1}{4}\)z - \(\frac{1}{8}\) | |
| -2z - \(\frac{3}{5}\) | |
| -z - \(\frac{1}{2}\) |
