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 -c - 2c = -3c - 7z - 6 for c in terms of z.
| -2\(\frac{1}{2}\)z - 3 | |
| -1\(\frac{3}{8}\)z + \(\frac{3}{8}\) | |
| \(\frac{1}{14}\)z - \(\frac{1}{14}\) | |
| -\(\frac{1}{10}\)z + \(\frac{1}{10}\) |
