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 - 7c = 9c - 7z - 5 for c in terms of z.
| \(\frac{1}{10}\)z - \(\frac{2}{5}\) | |
| -2z - 1\(\frac{1}{3}\) | |
| -\(\frac{1}{4}\)z - 1 | |
| z + \(\frac{5}{12}\) |
