Question 714943: So i keep getting questions like: 2x+15x=0 and i don't know how to solve them. I understand that you simplify first but what do you do after that? I know in problems like 2x+4x=25 you would subtract 25 from both sides but what about when it equals 0? Can somebody PLEASE take me through the steps of this prolem

2X+15X=0
(1)ELIMINATE 2X AND 15X
REPLACE THEM WITH (2+15)X ;;;;;;;;;;;;;;;;;;;;;(2+15)X=0
(2+15)X=0
(2)ADD FRACTIONS OR INTEGERS TOGETHER;;;;;;;;;;2+15=17
(17)X=0
(3)REMOVE THE PARENTHESES AROUND THE FACTOR;;;;17X=0
17X=0
17(1)=0
(5)REMOVE PARENTHESES AROUND THE FACTOR(1);;;;;17*1=0
17*1=0
MULTIPLY NUMERATOR INTEGERS;;;;;;;;;;;;;;;;;;;;17*0=0
RESULT=======17=0;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;17=0
SOLUTION===X=0;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;X=0
