Solve the system using elimination by addition.

#5
2x + 2y + 3z = 23
2x + 2y + 5z = 33
-4x - 4y - 8z = -55

don't u have 0 from the left if u add all those? oO

anonymous · Answer

thats correct

angela210793 · Answer

0=1??????? tht's not true....

anonymous · Answer

no solution

angela210793 · Answer

yea.... maybe...

anonymous · Answer

so there are no solutions then?

angela210793 · Answer

I think so...

anonymous · Answer

yes, 0 isn't equal to 1

anonymous · Answer

Can you explain clearer why there is no solution for this equation system?

angela210793 · Answer

If u know how to solve it...pls write it so i can learn as well :):)

anonymous · Answer

Not sure I can. However, because what you wrote before, I though you figured out at first glance that there was not a solution for the system lol. Im running out of time now. Gonna do it graphically and check if actually there is (not) a solution for the system. When I come back from work I'll solve it analytically

angela210793 · Answer

K...I'm waiting :):):)
well i said so cause when u add both parts u'll get 0=1...and tht's not true

anonymous · Answer

Yeah I ended up with something like that. Apparent there is not a solution for this system.
