2(2x-4)+x=7 
you use the distributive property...

2*2=4 
2*4=8
so you now have...
4x-8+x=7

then you add 4x+x and you get..
5x

so now its 
5x-8=7

to solve you would add 8 to both sides...
5x-8(=8)=7(+8)

which is...
5x=15

divide both sides by 5...
x=3

Wait lol was that a yes to u need help with it?

science_ally · Answer

yes please

anonymous · Answer

Oh okay one second.

anonymous · Answer

3(3x+8)-x= 8
distribute the 3 to both numbers

3*3= 9
3*8= 24

9x+24-x=8

now do 9x-x= 8x
8x+24=8

subtract 24 from both sides
8x+24(-24)=8(-24)

8x=-16

divide both sides by 8..

x=-2
