You can put this solution on YOUR website! the combined ages of joel his father and grandfather are equal to 100. joel is 25 years younger then his dad,and 51 years younger then his grand father , how old is joel his father and his grandfather
:
j + f + g = 100
:
" joel is 25 years younger then his dad,"
j = f - 25
Rewrite equation to
f = j + 25
:
"and 51 years younger then his grand father"
j = g - 51
rewrite equation to
g = j + 51
:
In the first equation replace f and g
j + (j+25) + (j+ 51) = 100
:
You should be able to do this now
, how old is joel his father and his grandfather
