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 2c - 9c = -7c - 2z - 6 for c in terms of z.
| z + \(\frac{2}{3}\) | |
| -\(\frac{2}{5}\)z + \(\frac{1}{15}\) | |
| -\(\frac{15}{17}\)z - \(\frac{5}{17}\) | |
| \(\frac{7}{9}\)z - \(\frac{2}{3}\) |
