Question

the solution of pair of linear equations x+y=13;x-y=3 is​

Answer 1

Answer:

x=8; y=5

Step-by-step explanation:

x+y=13

x-y=3

Hence, 2x= 16

and, x=8

x+y=13

8+y=13

y=5

Answer 2

Answer:

x=8,y=5

Step-by-step explanation:

X+y=13.....(1). x-y=3......(2)

multiplying equation 1,2 by 2,

then,

2x+2y=26

and..2x-2y=6

adding 3 and 4

2x+2y=26

2x-2y=6

________

4x. =32

x=32/4

X=8

put X=8 by equation X+y=13

8+y=13

y=13-8

y=5
