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 = -5c - 9z - 3 for c in terms of z.
| -\(\frac{14}{17}\)z + \(\frac{3}{17}\) | |
| -1\(\frac{1}{4}\)z - 1\(\frac{3}{4}\) | |
| -4z - 3 | |
| 10z - 8 |
