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 -5c - 4c = 6c - 8z - 2 for c in terms of z.
| 5z + 6 | |
| \(\frac{4}{11}\)z + \(\frac{2}{11}\) | |
| \(\frac{9}{13}\)z - \(\frac{3}{13}\) | |
| -1\(\frac{1}{2}\)z + 1\(\frac{1}{2}\) |
