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 + 2c = -9c - 9z + 2 for c in terms of z.
| -1\(\frac{1}{2}\)z - \(\frac{1}{2}\) | |
| 1\(\frac{1}{3}\)z + 1\(\frac{1}{3}\) | |
| -\(\frac{5}{12}\)z - \(\frac{1}{2}\) | |
| -\(\frac{11}{14}\)z + \(\frac{1}{7}\) |
