MARK BRAINLIEST
Step-by-step explanation:
3x + 2y = 10
2x + 3y = 15
x = 10 - 2y / 3
2(10 - 2y / 3) + 3y = 15
20 / 3 - 4y / 3 + 3y =15
-4y / 3 + 3y = 15 - 20/3
5y / 3 = 25 /3
15y = 75
y = 75/15
y = 5
2x + 3(5) = 15
2x + 15 = 15
2x = 15 - 15
2x =0
x =0/2
x =0
x = 0 y =5

Answer:
3x + 2y = 10 ------------- (i)
2x + 3y = 15 ------------- (ii)
Adding equation (i) and (ii) , we get :
3x + 2y = 10
2x + 3y = 15
therefore,
3x + 2x + 2y + 3y = 10 + 15
5x + 5y = 25
= 5 (x + y) = 25
= x + y = 25 / 5
= x + y = 5
Hope it helps
