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 -9c - 9c = -5c - 8z + 9 for c in terms of z.
| -\(\frac{1}{4}\)z - 2\(\frac{1}{4}\) | |
| \(\frac{1}{3}\)z + \(\frac{1}{6}\) | |
| -1\(\frac{2}{3}\)z - \(\frac{1}{3}\) | |
| -\(\frac{1}{12}\)z - \(\frac{5}{12}\) |
