Question

solve the following linear equation x+y=10 ,x-y=2
​

Answer 1

Step-by-step explanation:

x+y= 10

x- y= 2

adding both

2x= 12

x=6

putting into x+y=10

6+y=10

y=10-6

y=4

I hope it is helpful

mark me brainlist......... plzzzzzzz......

Answer 2

Answer:

Step-by-step explanation:

x+y=10. ...............(1)

x-y=2

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

Substitute (2)in (1)

x+y=10

2+y+y=10

2+2y=10

2y=10-2

2y=8

y=8/2

y=4

x+y=10

x+4=10

x=6

Therefore

(x,y)=(6,4)
