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 - 2c = -5c + 9z - 5 for c in terms of z.
| z - 1\(\frac{1}{3}\) | |
| -3z - 8 | |
| -\(\frac{9}{14}\)z - \(\frac{2}{7}\) | |
| 5\(\frac{1}{2}\)z - 2\(\frac{1}{2}\) |
