Question

Elimination method of 2x+y=35,3x+4y=65​

Answer 1

Step-by-step explanation:

2x +y = 35........(1)

3x +4y = 65........(2)

Multiply (1) by 4=>

8x +4y = 140........(3)

Now solve (2)&(3)

(3)-(2)

8x +4y = 140

3x +4y = 65

- - -

_____________

5x = 75

x = 15

substitute x = 15 in (2)

3x +4y = 65

3(15) + 4y = 65

4y = 65-45

4y = 20

y = 5

So,

(x,y) = (15,5)

Answer 2

Answer:

answer is

Step-by-step explanation:

2x+y=35,3x+4y=65

=2x+3x+4y+y=65-35

=5x+5y=30

=5(x+y)=30

=(x+y)=30/5

=(x+y)=6

therefore x+y=6

sorry bro Maine dhyan Nhi diya ki kis method me Karna hai.

plz mark the brilliant answer
