Answer:
x= 17
y= 28
Step-by-step explanation:
x = jagruti
y = aunt
---
(x + 5) = (2/3)(y + 5)
(x - 3) = (1/2)y
---
put the system of linear equations into standard form
---
x + 5 = (2/3)y + 10/3
x - 3 = (1/2)y
---
x - (2/3)y = 10/3 - 15/3
x - (1/2)y = 3
---
x - (2/3)y = -5/3
x - (1/2)y = 3
---
3x - 2y = -5
2x - y = 6
