Answer 2

Answer:

Step-by-step explanation:

0.5x+0.8y=3.4 ...(1)

0.6x-0.3y=0.3​....(2)

taking equation (1)

0.5x+0.8y=3.4 ...(1)

0.5 x = 3.4 - 0.8 y

x =   3.4 - 0.8 y /0.5...(3)

Putting value in equation (2)

0.6x-0.3y=0.3​

0.6  × 3.4 - 0.8 y /0.5-0.3y=  0.3​

2.04  - 0.48 y - 0.15y / 0.5 = 0.3

2.04 - 0.33y  = 0.3 × 0.5

0.33y = 0.15 - 2.04

y = -1.89 / 0.33

y = - 5.72
