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 - 5c = -2c + 2z - 6 for c in terms of z.
| -3z + 3 | |
| \(\frac{3}{4}\)z + \(\frac{1}{2}\) | |
| -z + \(\frac{6}{7}\) | |
| \(\frac{5}{6}\)z - \(\frac{1}{12}\) |
