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