Question

write three solutions of te following equation 2x+y=14​

Answer 1

Answer:

ANSWER

Given:   2x−3y=−14...(1)

             3x−2y=−6...(2)

After adding (1) and (2) equations. we get

2x−3y+3x−2y=−14−6

⇒5x−5y=−20⇒x−y=−4...(3)

On subtracting (1) from (2). we get

3x−2y−2x+3y=−6+14

⇒x+y=8...(4)

Now adding (3) and (4). we get

2x=4⇒x=2

By putting x=2 in (3), we get

2−y=−4⇒y=6

∴(2,6) is solution of given equations.

Value of xy=2×6=12.

Answer 2

Answer:

2x+y=14. (1)

x-y=1. (2)

2x+y=14

x-y=1

3x=15,x=15/3=5,x=5

5-y=1,y=5-1=4,y=4
