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 8c + 8c = -7c - 3z - 5 for c in terms of z.
| -\(\frac{8}{13}\)z + \(\frac{9}{13}\) | |
| 1\(\frac{2}{5}\)z - 1\(\frac{4}{5}\) | |
| 2\(\frac{1}{3}\)z + 2\(\frac{2}{3}\) | |
| -\(\frac{11}{15}\)z - \(\frac{1}{3}\) |
