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 c - 9c = -4c - 6z - 2 for c in terms of z.
| \(\frac{1}{5}\)z + 1\(\frac{1}{5}\) | |
| \(\frac{7}{10}\)z + \(\frac{7}{10}\) | |
| 4z - 4 | |
| \(\frac{3}{5}\)z - \(\frac{2}{5}\) |
