Question

0.6x+0.5y=5,0.8x+0.1y=4.4

Answer 1

0.6x+0.5y=5 -(1)

0.8x+0.1y=4.4 -(2)

Multiply equation 1 & 2 by 10

6x+5y=50 -(3)

8x+1y=44 -(4)

By elimination method

multiply equation 4 by 5

40x+5y=220

6x+5y=50

40x+5y=220

Subtract

-34x= -170

34x=170

x=170/34

x=5

putting the value of x in equation 3

6(5)+5y=50

30+5y=50

5y=50-30

5y=20

y= 20/5

y = 4
