Question

1.draw the graph for x-y+1=0,3x+2y-12=0. calculate the area bounded by these lives &x-axis.

2. solve the following pair of linear equation:-

1) 2x-3y=7 & x+y=1

2) x+1/2+ y-1/3=8 & x-1/3+y+1/2=9

3) 3(2u+v)=7uv & 3(u+3v)-11uv

4) 1/2x+1/3y=2 &1/3x+1/2y=13/6

Answer 1

no time sorry but welcome
