Question

If 2x + 3y = 10 and 3x + 2y = 15, find the value of (x + y) ​

Answer 1

Answer:

2x+3y=10

3x+2y=15

adding,

5x+5y=25

=> 5(x+y)=25

=> x+y=25/5

=> x+y=5

Answer 2

Answer:

x = 5

y = 0

Step-by-step explanation:

2x + 3y = 10 ( 1 )

3x + 2y = 15 ( 2 )

subtracting 1 from 2 we get x - y = 5

x = y + 5 ( 3 )

applying 3 in 1 we get 2(y + 5 ) + 3y = 10

that is 2y + 3y = 0

5y = 0

y = 0

therefore x = 5.
