You can put this solution on YOUR website!
3-|2X+1|=0
-3+3-|2x+1|=0-3
-|2x+1|=-3
-|2x+1|/-1=-3/-1
|2x+1|=3
2x+1=3 or 2x+1=-3
2x+1-1=3-1 or 2x+1-1=-3-1
2x=2 or 2x=-4
2x/2=2/2 or 2x/2=-4/2
highlight%28x=1%29 or highlight%28x=-2%29
Check:
when x=1
3-|2(1)+1|=0
3-|2+1|=0
3-|3|=0
3-3=0
0=0 We're right!!!
when x=-2
3-|2(-2)+1|=0
3-|-4+1|=0
3-|-3|=0
3-3=0 We're right again!!!
Happy Calculating!!!
