Question

(i) 2x+3y = 10 आणि 3x+2y = 15 साठी (x+y) ची किंमत काढा.​

Answer 1

Explanation:

2x+3y=10. (1)

3x+2y=15. (2)

add equation (1) and (2) we get,

5x+5y=25

x+y=25/5

x+y=5

Answer 2

GIVEN:-

(i) 2x+3y = 10 आणि 3x+2y = 15 साठी (x+y) ची किंमत काढा.

SOLUTION:-

2x + 3y = 10 (i)

3x + 2y = 15 (ii)

by multiplying (i) to 3 and (ii) to 2.

we get,

6x + 9y = 30 (iii)

6x + 4y = 30 (iv)

subtracting (iv) from (iii)

we get,

5y = 0

y = 0. (v)

putting the value of (v) in (i)

we get,

2x + 3y = 10

2x + 3(0) = 10

2x = 10

x = 5.

Therefore,

x = 5 and y = 0.

And (x+y) = (5+0) = 5.
