Question 105214
Simplify: {{{3(x-1) - 2(-x+2)}}}

{{{ 3(x-1) - 2(-x+2)}}}      first look at {{{ 3(x-1)}}} and {{{ -2(-x+2)}}};  expande term {{{3}}} by using associative property on {{{(x-1)}}}, and expande term {{{-2}}} by using associative property on {{{(-x+2)}}}.

then you have

{{{3x - 3 + 2x - 4}}}

which is {{{equal}}} to

{{{5x - 7}}}
