Step-by-step explanation:

 =  > Let \:  0.2x+0.3y=1.3       ....(1)

 =  > 0.4x+0.5y=2.3       ....(2)

 =  > Multiply \:  eqn(1) by \:  10 we \:  get

 =  > 2x+3y=13                ....(3)

 =  > Multiply  \: eqn(2) by \:  10 we  \: get

 =  > 4x+5y=23                ....(4)

 =  > Solving  \: equations (3) and (4)

 =  > 5×(3)⇒10x+15y=65

 =  > 3×(4)⇒12x+15y=69

 =  > Subtracting \:  we \:  get  \: 12x+15y−10x−15y=69−65=4

 =  > or 2x=4 or x=2

 =  > Substituting \:  x=2 in  \: eqn(3) we \:  get

 =  > 2x+3y=13⇒2×2+3y=13 or 3y=13−4=9 or y=3

 =  > Hence \:  x=2,y=3
