please answer me this question

Answer:
x=0.4 and y=0.6
Step-by-step explanation:
Given :
[tex]\frac{x}{2} +y=0.8\\x+2y=1.6.......(1)\\\frac{7}{x+y/2} =10\\\frac{7}{2x+y/2} =10\\\frac{7*2}{2x+y} =10\\\frac{14}{2x+y} =10\\14=10(2x+y)\\14=20x+10y.....(2)[/tex]
From solving above equation (1) and (2)
x=0.4
y=0.6
