Answer 2

Answer:

your answer is 6

Step-by-step explanation:

Given that the two eq.......

2x-y=3............eq(1)

-x+2y=3.........eq(2)

now we multiply eq(2) with 2

we get,

-2x+4y=6.......eq(3)

so now we add eq(1) with eq(3)

we get,

2x-y=3

+

-2x+4y=6

_______________

3y=9

y=9/3=3

we find the value of y =3

so put the value of y in eq(1)

2x-y=3

=>2x-3=3

=>2x=6

=>x=3

now we find the both value of x and y....

now we easily solve the question....☺️

the value of x+y =3+3= 6

hope it will help you ☺️
