Question

solve by elimination method and verify the answer 2x+y=8, x+y=5​

Answer 1

Answer:

2x+y=8

x+y=5.

so x +x+y= 8

x+(x+y)=8

x+5 =8

x=8-5

x=3

x+y= 5

3+y=5

y=5-3

y=2

Answer 2

Here we have, 2x+y=5→(1)

3x+2y=8→(2)

Let Multiply eq n (1) by 2.

So, 4x+2y=10

4x+2y=8

x=2

In the eq n (1), put x=2,4+y=5

So,

x=1

(x,y)=(2,1)

Hope it helps.
