Question

If I add 7 times my age seven years from now and 3 times my age
three years ago, I get 12 times my current age. How old will I be 3 years
from now?
​

Answer 1

Answer:

32yrs

Step-by-step explanation:

let, present age =x

from the question:-

7(x-7)+3(x-3)=12x

7x-49+3x-9=12x

10x-58=12x

10x-12x=58

-2x=58

x=58/-2=-29

but age can't be negative so, present age =39 age after three years =29+3=32yrs

I hope my answer helps you ☺☺

Answer 2

Step-by-step explanation:

Description

Three years ago X-3

Present age x

Seven years hence x+71

If I add seven times my age seven years from now, to three times my age three years ago, I get 12 timesmy current age.

7(x+7) + 3(x-3) = 12x

X = 20

Three years from now =x+ 3 = 20 +3= 23
