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 -3c - 5c = -9c + 3z + 5 for c in terms of z.
| 1\(\frac{1}{3}\)z + \(\frac{5}{6}\) | |
| 1\(\frac{2}{7}\)z + \(\frac{2}{7}\) | |
| -z + \(\frac{7}{12}\) | |
| \(\frac{3}{11}\)z + \(\frac{3}{11}\) |
