the following linear equations (Q.1-0.7)​

Answer 1

Answer:

answer for third question is

son is 6 years

man is 30 years

Step-by-step explanation:

let the present age of son be x

present age of man be 5x

before 2 years

son=x-2

man=5x-2

so,

7(x-2)=5x-2

7x-14=5x-2

7x-5x=-2+14

2x=12

x=6

thus , son is 6 yrs and man is 5 times of six (30)
