Answer:

hey here is your solution

pls mark it as brainliest

so here we go

Step-by-step explanation:

let the age of my father be x years and that of mine be y years

so according to first condition

x-5+2y=65

ie x+2y=70 (1)

according to second condition

y-5+3x=130

so 3x+y=135 (2)

multiply (2) by 2

we get

6x+2y=270 (3)

so subtract (1) from (3)

we get

6x+2y=270

x+2y=70

(-) (-) (-)

_________

5x=200

thus x=40

so present age of my father is 40 years
