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 2c - c = -7c - 9z - 7 for c in terms of z.
| \(\frac{1}{8}\)z - \(\frac{3}{8}\) | |
| -\(\frac{8}{9}\)z - \(\frac{7}{9}\) | |
| \(\frac{3}{5}\)z - \(\frac{3}{10}\) | |
| -\(\frac{1}{2}\)z - \(\frac{1}{14}\) |
