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 = 8c - 9z - 4 for c in terms of z.
| -\(\frac{1}{17}\)z + \(\frac{5}{17}\) | |
| z - 4 | |
| 7z + 6 | |
| -3z + 2\(\frac{1}{2}\) |
