Question

The solution for the equation 3x+y=25 and 3x-y=5

Answer 1

The answer is is X=5,Y=10

Answer 2

The answer is x = 5 , y = 10

Explanation:

given,

3x+y=25...........(i)

and

3x-y=5.............(ii)

Now,

adding both the equation (i) and (ii),

we get,

3x + 3x = 25+ 5

=> 6x = 30

=> x = 30/6

=> x = 5

Now,

putting the value of x in eqn (i),

we get,

3×5 + y = 25

=> 15 + y = 25

=> y = 25 - 15

=> y = 10

HENCE,

x = 5

y = 10

Hope it will help you .
