Question 684166
Take it a few words at a time
" three more than" is {{{ +3 }}}
" three times a number" is {{{ 3n }}}
So far you've got {{{ 3n + 3 }}}
-------------------------
"is" means " = "
" one less than " is {{{ -1 }}}
" two times the number is {{{  2n }}}
So, you have {{{ 2n - 1 }}}
-------------------------
Put the two sides of the " = " sign together:
{{{ 3n + 3 = 2n - 1 }}}
and you can solve for {{{ n }}}
{{{ n + 3 = -1 }}}
{{{ n = -4 }}}
