Question

solve:2x+y=11 x+y=8​

Answer 1

Given data,

$2x + y = 11 \: \: \: \: \: \: ..(1) \\ x + y = 8 \: \: \: \: \: \: \: ...(2)$

To calculate,

$x \: and \: y$

Calculation,

$subtracting \: equation \: (2) \: from \: eqution \: (1) \\ we \: get \\( 2x + y) - (x + y) = 11 - 8 \\ 2x + y - x - y = 3 \\ x = 3 \\ substituting \: the \: vaue \: of \: x \: in \: equation(1) \\ we \: get \\ 3 + y = 8 \\ y = 5$

Final answer,

$(x,y)is \: (3,5)$

hope it helps to you☺️

Answer 2

Answer:

Step-by-step explanation:

2x+y=11. -eq (1)

x+y=8 -eq (2)

Subtracting eq (1) by eq (2)

2x+y-(x+y)=11-8

2x+y-x-y=3

2x-x+y-y=3

x=3

Now put the value of x=3 in eq (2)

x+y=8

3+y=8

y=8-3

y=5

So, your answer is :-

x=3

y=5
