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