OpenStudy (campbell_st):
ok.. so multiply the 1st equation by 3 and add the new equation to the 2nd equation. What do you get...?
OpenStudy (otonogold):
Im confused. @campbell_st
OpenStudy (campbell_st):
ok divide the 2nd equation by -3 you get 3x + 3y = 10 so what do you notice....
OpenStudy (otonogold):
Oh they end up as the same equation at the first one.
OpenStudy (campbell_st):
correct... so the 2nd equation is just a multiple of the 1st... so they are the same line.... now you can comment on the solutions.
