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 - 6c = -5c - 7z + 4 for c in terms of z.
| -\(\frac{4}{5}\)z - \(\frac{4}{15}\) | |
| -\(\frac{1}{8}\)z + \(\frac{1}{2}\) | |
| -\(\frac{1}{4}\)z + 1\(\frac{3}{4}\) | |
| z - 4 |
