Question

0-21 + 0-1) = 25
2x - 2) - 1-6y = 116​

Answer 1

Answer:

Step-by-step explanation:

0.2x+0.1y=25...(i)

2(x−2)−16y=116...(ii)

By solving (ii) eq.

2x−4−16y=116

2x−1.6y=120

x−0.8y=60×2

0.2x+0.1y=25×8

⇒x−0.8y=60

1.6x+0.8y=200

2.6x=260

x=  

216

2600

​  

 

x=100

∴0.2(100)+0.1y=25

20+0.1y=25

0.1y=5

y=00
