Multiply first equation by 3. Subtract third equation. You will get an equation in x and y. Multiply first equation by 4. Subtract second equation. You will get another equation in x and y. Now, solve for x and y using these two new equations. Then, substitute back the values of x and y into one of the three to get z.
