Question

if 3x+2y=10and 2x+3y=15 then find the value of x+y​

Answer 1

Step-by-step explanation:

3x+2y=10

3x=10-2y

x=10-2y/3

2x+3y=15

2x=15-3y

x=15-3y/2

value of x will be same

hence,

10-2y/3=15-3y/2

2(10-2y)=3(15-3y)

20-4y=45-9y

9y-4y=45-20

5y=25

y=25/5

y=5

therefore,

x=15-3y/2

=15-3(5)/2

=15-15/2

=0/2 =0

ans. y=5,x=0
