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 = -5c - z + 5 for c in terms of z.
| \(\frac{1}{2}\)z - \(\frac{5}{8}\) | |
| 2\(\frac{2}{3}\)z + 1\(\frac{2}{3}\) | |
| 12z - 9 | |
| -\(\frac{3}{10}\)z + \(\frac{9}{10}\) |
