Answer:

1) I'm 15and my father is 45approx

so if my age is x then my father's is 3x

now: x+3x=0

after 10yrs : 10(x+3x) =0

2) now here I take 2distribution situation

x=expenditure on food

4y=house rent ( I take it as 4 y because my house rent is 4 times expenditure on food)

linear equation: x+4y=0

x=extras like stationary etc

3y=education ( I take it as 3 y because extras is 3 times education)

3) 10x+y=20

10y+2x=40

4) it takes 1hr fr me to go to school by walk and approx of half an hour by bus

idk actually how to form an equation.. sry
