Question

2x + 5y =20____(1) 3x + 6y =12_____(2) plz solve by elimination​

Answer 1

Step-by-step explanation:

2x+5y=20×3

3x+6y=12×2

6x+15y=60

6x+12y=24

(-) (-) (-)

----------------

0x+3y=36

y=36÷3

y=12

2x+5(12)=20

2x+60=20

2x=20-60

2x= -40

x= -40÷2

x= -20

Answer 2

Answer:

2x+5y=20.....................(1)

3x+6y=12......................(2)

Multiplying equation (1) by 3 &(2) by 2 we get,

6x+15y=60................(3)

6x+12y=24................(4)

Subtracting eq(4) from (3), we get,

3y=36

y=36/3=12

x=-20
