Answer:
x=0.5,y=0.7
Step-by-step explanation:
0.3x+0.5y=0.5
0.5x+0.7y=0.74.
Multiply both the equations by 10, we get
3x+5y=5...(1)
5x+7y=7.4...(2)
Multiply (1) by 7 and (2) by 5. And subtract both the equations.
−4x=−221x+35y=3525x+35y=37−−−
x=−4−2=21=0.5
Substitute the value of x in equation (1), we have
3(0.5)+5y=5
y=0.7
Answer : x=0.5 and y=0.7
