Not the answer you are looking for? Search for more explanations.
after doing the manipulation i told u will get an equation in y and z
3y + 2z = 3
then add second and third equation...x gets weliminated..and u get another equation in y and z
see the first equation is -2x+2y+3z=0
second equation is -2x-y+z=-3
third equation is 2x+3y+3z=5
now simply add equation 1 and 3 x gets eliminated
and again add equation 1 and 3 x gets eliminated...
u will hav two equation in y and z
then get values of y and z ang plug them in any of the given three equation
