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 -2c + 9c = c + 8z + 8 for c in terms of z.
| 4\(\frac{1}{4}\)z - \(\frac{3}{4}\) | |
| \(\frac{1}{10}\)z + \(\frac{2}{5}\) | |
| \(\frac{1}{3}\)z - 2\(\frac{2}{3}\) | |
| -\(\frac{3}{4}\)z - \(\frac{3}{4}\) |
