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 + c = 3c - 8z - 6 for c in terms of z.
| -\(\frac{7}{9}\)z + \(\frac{7}{9}\) | |
| -1\(\frac{1}{2}\)z - 1 | |
| 2\(\frac{1}{3}\)z + 2\(\frac{1}{3}\) | |
| -3z - \(\frac{1}{3}\) |
