Let x be the age of his Brother
Therefore, John's Age will be
y = 6 + x (first equation)
In 4 years
y + 4 = 2(x + 4) (second equation)
Now let's substitute the value of y from the first equation to the second equation
(6 + x) + 4 = 2(x + 4)
Add 6 and 4; Multiply 2 to x + 4
10 + x = 2x + 8
Transpose x and 8
10 - 8 = 2x - x
Therefore the age of his brother is
x = 2
Now let's substitute the value of x to the first equation
y = 6 + 2
Therefore John's age is
y = 8
Now let us check if adding 4 to both will make John's age twice as his brother
after 4 years
x = 2 + 4
x = 6
---
y = 8 + 4
y = 12
12 is twice as 6. Therefore it is correct.
I hope it helps
