Question

Solve the following pair of linear equation by elimination method.2x+y=6 and 3x+2y=11

Answer 1

Step-by-step explanation:

3(2x+y=6)&2(3x+2y=11)

6x+3y=12&6x+4y=22

6x+3y=12

6x+4y=22

- - -

= -y=-10

= y=10

2x+10=6

2x =6-10

x=-4/10

x=-2/5

Answer 2

Answer:

Step-by-step explanation:

(2x+y=6)×2 = 4x+2y-12

-(3x+2y)=11 = -3x -2y+11

= x - 1

x = 1 then y = 6 - 2(1) = 4

Then y = 4

Verification

x, y is substitute in 2x+y = 6

2(1) +( 4) = 6

2+4 = 6

6=6
