Question 517980
Let {{{ x }}} = the number of years until
the father is 3 times older than the son
{{{ 22 + x = 3*( 2 + x ) }}}
{{{ 22 + x = 6 + 3x }}}
{{{ 2x = 16 }}}
{{{ x = 8 }}}
In 8 years the father will be 3 times older than the son
check:
In 8 years the father will be 22 + 8 = 30
In 8 years the son will be 2 + 8 = 10
The father will be 3 times older
