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