(1
After 10 years, I will be twice as old as 5 years ago, what is my present-age?
please any body give step by step answer of this linear equation!!​

Answer 1

Answer:

the answer is 7.5

Step-by-step explanation:

10=2x-5

x=10-5/2

x=7.5

Answer 2

Answer:

let the present age be x

according to the question,

x- 10=2(x-5)

x-10=2x-10

2x-x=10+10

x=20

therefore present age is 20

Step-by-step explanation:

after 10 years means 10 years + the current age

twice as old as 5 years ago means he will be twice his AGE.

AGE means his age 5 years ago the present age

let the present year be 2020. Then the year after 10 years will be 2030. But 5 years ago in the second part of the question mean he is talking about 2015.
