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 -5c - 8c = -6c + 9z - 2 for c in terms of z.
| -2z - 3 | |
| -9z + 8 | |
| 17z - 2 | |
| -1\(\frac{2}{13}\)z - \(\frac{3}{13}\) |
