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 9c + 3c = -7c + z - 2 for c in terms of z.
| \(\frac{1}{2}\)z - \(\frac{3}{7}\) | |
| \(\frac{3}{4}\)z + \(\frac{3}{4}\) | |
| -\(\frac{1}{8}\)z - \(\frac{1}{8}\) | |
| -\(\frac{3}{4}\)z - \(\frac{3}{8}\) |
