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 -6c - 6c = -9c + 4z + 8 for c in terms of z.
| 4z - 4 | |
| 3\(\frac{1}{3}\)z + 2\(\frac{2}{3}\) | |
| \(\frac{5}{7}\)z - 1 | |
| z + \(\frac{2}{11}\) |
