Answer:

older person = 29

youth = 5

Step-by-step 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
