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 - 9c = -4c + 2z - 4 for c in terms of z.
| 1\(\frac{2}{3}\)z - 2\(\frac{1}{3}\) | |
| 2\(\frac{1}{7}\)z + \(\frac{1}{7}\) | |
| -2z - 2 | |
| -5\(\frac{1}{2}\)z + 2 |
