Question 417189
five less than three times a number is the same as eight times the number. 

Let the number = x

three times a number = 3x


five less than three times a number = 3x-5

eight times the number = 8x

five less than three times a number is 
the same as eight times the number==>  3x-5  = 8x

==> {{{ 3x-5+ 5  = 8x +5 }}}

==> {{{3x   = 8x +5 }}}

==> {{{3x - 8x  = 8x +5 - 8x }}}

==> {{{-5x   =  5 }}}

==> {{{-5x/-5   =  5/-5}}}

==> {{{ x   = -1}}}
