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 -4c - 5c = -6c + 9z - 5 for c in terms of z.
| -\(\frac{1}{10}\)z - \(\frac{4}{5}\) | |
| -3\(\frac{2}{3}\)z + \(\frac{2}{3}\) | |
| z + 8 | |
| 7z - 2\(\frac{1}{2}\) |
