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 -9c + 4c = c - 5z + 2 for c in terms of z.
| -\(\frac{8}{9}\)z - \(\frac{5}{9}\) | |
| -2z - 6 | |
| \(\frac{9}{10}\)z - \(\frac{1}{5}\) | |
| 7z - 4 |
