Question 550456
wrong section but simply use the addition property and group like terms
{{{9y}}} ask are there any other single y variables...nope
{{{b}}} are there any other single b variables...yess add them together {{{b+b+b=3b}}}
{{{-7g}}} are there any other single g variables...nope
{{{-8xg}}}are there any other xg variables...nope
{{{-3yg}}}are there any other yg variables...nope
{{{-2x}}}are there any other single x variables...nope
{{{highlight(9y+3b-2x-7g-8xg-3yg)}}}
now its simplified but it can be rearranged differently depending on what your teacher is looking for
1 possibility
{{{9y+3b-2x+(-7g-8xg-3yg)}}}
{{{9y+3b-2x-g(7+8x+3y)}}}
{{{highlight(3(3y+b)-2x-g(7+8x+3y))}}}
2 possibility
{{{3b-7g(-2x-8xg)+(9y-3yg)}}}
{{{highlight(3b-7g-2x(1+4g)+3y(3-g))}}}
there are a few more but i was just giving u the ideas
