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 + 6c = -2c - 7z - 2 for c in terms of z.
| -2\(\frac{5}{6}\)z + \(\frac{2}{3}\) | |
| -2\(\frac{3}{5}\)z - \(\frac{2}{5}\) | |
| 2\(\frac{2}{7}\)z - \(\frac{5}{7}\) | |
| -6z - 2\(\frac{1}{2}\) |
