	x = -3 and x = 1
	no solutions

hexagon001 · Answer

look at 2 situations...
1) 2x+6 -4 =20 
    2x +2 =20
    2x =20-2
   2x =18
    x=18/2
     x=9


2) -2x-6-4=20
     -2x-10=20
      -2x =20+10
       -2x =20
         x= 20/-2
         x=-15

so x=-15 and 9

20+10 = 20? ( but yeah ans is correct)

anonymous · Answer

love you thank you

hexagon001 · Answer

do you get it? 

for one solution you take what is inside the modulus sign to be all positive and solve it...
for the second solution take all in the modulus sign to be negative and then solve it.

@luckythebest  woopsy that is supposed to read 30

hexagon001 · Answer

@luckythebest and @InsanelyChaotic 
i typed fast an never realised error.. change the 20 +10 =20 to 20+10=30 and all the subsequent 20s to 30...

anonymous · Answer

yes, that makes a lot more sense... wow:)
