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 4c - 4c = -9c - 7z - 3 for c in terms of z.
| -\(\frac{3}{13}\)z - \(\frac{3}{13}\) | |
| -2\(\frac{1}{4}\)z + \(\frac{3}{4}\) | |
| -2z + \(\frac{4}{5}\) | |
| -\(\frac{6}{11}\)z - \(\frac{2}{11}\) |
