2) 2x + 3y= 11
-x-5y=-23

one solution (-2 ; 5)

Step-by-step explanation:

hello :   2x + 3y= 11 ...(*)

           -x-5y=-23(**)

by(**) : x= -5y+23

put this value into (*) :  2(-5y+23)+3y=11

-10y+46+3y=11

-7y = -35

y=5

but x= -5y+23

so :  x= -5(5)+23 =-2

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
