Question

Henry is 20 years older than George. In 5 years, Henry will be twice as old as George is then. Find their present ages.

Answer 1

h = g+20

h+5 = 2g

g+20+5 = 2g

g+25 = 2g

25/2 = g ..... really? what i miss?

Answer 2

h = g+20

h+5 = 2(g+5) maybe

g+25 = 2g +10

15 = 2g ..... murmur

Answer 3

gotta go; good luck ;)

Answer 4

Henry is 45 and George is 25

The question states that: George is 20 younger than Henry (G=H-20)

In five years, Henry will be 2 times as old as Gorge at present day (H+5=2G)

Plug in G=H-20 into H+5=2G and solve for H then plug H (45) into the original formula to find that G is 25

Answer 5

Thank you!
