Question

solve x+2y=11,2x+y=10 ​

Answer 1

Answer:

x=3,

y=4

Step-by-step explanation:

2x +y = 10

y=10-2x

x+2y=11

x+2(10-2x)=11

x+20-4x=11

20-3x=11

3x=9

x=3

x+2y=11

3+2y=11

2y=8

y=4

Answer 2

Answer:

x+2y=11...eq1

2x+y=10...eq2

Multiply eq1 by 2

2x+4y=22

Subtracting eq1 by eq2

On solving we get y=4

Substituting y in eq1

We get x=3

Therefore x=3 and y=4
