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