5x-2+3x-4 = 2x-8+x+2

First we have to put all X's on side and the remaining numbers on the other, changing their signal if they move across the equal sign. Therefore,

5x+3x-2x-x = -8+2+4+2
5x = 0
x= 0/5
x= 0
Solving an equation means finding a value of a variable that make the equation true. This value is called the solution of the equation. A mathematical equation is just like a balanced equation. Both sides of the equation should be equal at all times. Whatever we do to one side, has to be done on the opposite side.

[tex]5x-2+3x-4=2x-8+x+2[/tex] 

[tex]8x-2-4=2x-8+x+2 [/tex] 

[tex]8x-6=2x-8+x+2 [/tex] 

[tex]8x-6=3x-8+2 [/tex] 

[tex]8x-6=3x-6 [/tex] 

[tex]8x=3x[/tex]      [tex]Cancel \ -6 \ on \ both \ sides[/tex] 

[tex] 8x-3x=0 [/tex]  [tex]Move \ all \ terms \ to \ one \ side[/tex]

[tex] 5x=0 [/tex]  

[tex] 5x/5=0/5 [/tex]        [tex]Divide \ both \ sides \ by \ 5[/tex]

[tex]x=0[/tex]
