Answer:
The answer is x= 6.2 and y= 5.7
Step-by-step explanation:
Let the two numbers be x and y.
1st condition:
x+y= 11.9 --- (1)
2nd condition:
x-y=0.5--- (2)
Solving 1 and 2
x+y= 11.9 --- (1)
x-y=0.5--- (2) (here +y and -y will get cancelled)
_____________
2x= 12.4
x= 12.4/2 = 6.2
∴x= 6.2
Now, put x= 6.2 in equation (1) ( u can put in eqn 2 also)
6.2+y= 11.9
y= 11.9-6.2= 5.7
∴y= 5.7
To recheck you can put the value of x and y in any of the eqns.
The LHS will be equal to RHS if the values we got are correct.
Hope it helps.
