Question 382736
The difference between two numbers is 8. The sum of five times the larger number and the smaller number is 160. What are the two numbers?
Sol'n:
 let: x - the larger number
      y - the smaller number
 x-y=8 ----(1)
 5x+y=160 ----(2)
from (1)
 x=8+y
substitute to (2)
 5(8+y)+y=160
 40+5y+y=160
 6y=160-40
 6y=120
  y=20
for x:
 x=8+20
 x=28
thus:
 x=28 & y=20 ----answer
