A few times. It's pretty hard headed.

j = s+2

s = h-4 so far :)

amistre64 · Answer

h+4 = j+s

amistre64 · Answer

h = s+4

s+4+4 = s+2 + s+4-4

amistre64 · Answer

s+8 = 2s +2

6 = s ; but lets dbl chk that lol

amistre64 · Answer

j = 8; s = 6; h = 10  to start with

in 4 years h = 14

14 = 8+6; got it :)

The question is basically saying: 
June is 2 years younger than Hal==> J=H-2
Sara is 4 years younger than Hal==>S=H-4

In four years, Hal will be four years older==> H+4 which will be equal to the sum of Sara and June's current age

Therefore,

H+4=H-2+H-4

Solve for H,

You get, 10
Plug in 10 for H in June and Sara's equation from the first year

You get:
Sara=H-4
= 10-4
= 6

June=H-2
= 10-2
=8
