Question

An older person is nine years older than four times the age of a younger person for some of their age is 34 find their ages

Answer 1

the anser is 60 something

Explanation:

Answer 2

older person = 29

youth = 5

Explanation:

Let old = x

Let young = y

x + y = 34 transfer y to the right side

x = 34 - y

x = 4y + 9 Transfer the 4y to the left

x - 4y = 9 Substitute the modified first equation for y.

34-y - 4y = 9 Combine

34 - 5y = 9 Subtract 34 from both sides

-5y = -25 Divide by - 5

y = -25/-5

y = 5

x + y = 34

x + 5 = 34

x = 34 - 5

x = 29
