Jerry solved the system of equations. x-3y= 1 7x+2y=7 as the first step, he decided to solve for y in the second equation because it had the smallest number as a coefficient. max told him that there was a more efficient way. what reason can max give for his statement?

Prism m and pyramid n have the same base area and the same height. cylinder p and prism q have the same height and the same base perimeter. cone z has the same base area as cylinder y, but its height is three times the height of cylinder y. the figures and have the same volume.
