Question

sum of two numbers is 42 and their difference is 8. find the number?​

Answer 1

Step-by-step explanation:

x+y =42 ....... 1

x-y =8 ............2

.... add eqn 1 and 2....

2x = 50

x= 25

subsitituting th value of x = 25 in eqn 2

25-y = 8

y = 25-8

y = 17

x= 25 and y = 17

Answer 2

Answer:

x=25. y=17.

Step-by-step explanation:

x+y=42 - i

x-y=8 -ii

from i

x=y+8

y+8+y=42

2y=42-8

y=34/2

y=17

If y=17

x=17+8

x=25
