Question 135491: INDICATE WHETHER THE EQUATION HAS NO SOLUTION OR IS TRUE FOR ALL REAL NUMBERS. IF NIETHER IS THE CASE, SOLVE FOR THE VARIABLE.

18x-3(3+6x)=-9....Use the Distributive Property (remember, since there is a minus sign in front of the "3", you have to distribute it as a "-3")
18x-9-18x=-9...."18x" and "-18x" cancel out
-9=-9.....ALL REAL NUMBERS
