NOw:
brother is x
Ria is x+6

brother was x-14
Ria was x+6 - 14 = x - 8
x - 8 = 2(x - 14)
solve for x and you'll know everything

r = b + 6

r - 14 = 2(b - 14)

substituting ... b + 6 - 14 = 2 b - 28

solve for b , then substitute back to find r

We can create a chart.
Present:
brother - x
Ria - x+6

14 years ago:
brother was x-14
Ria was x+6 - 14
According to the second part of the problem, we know that:
x - 8 = 2(x - 14)
After solving the equation, you'll get the answer as: x=20
So, Ria's brother is 20. Since Ria is x+6, then:

Brother=20
Ria=26
