3x - 7 = 5x + 19
  |Equation|


-7=5x+19-3x
 
  |Subtract \ 3x \ from \ both \ sides| 


-7=2x+19
 
 


-7-19=2x
 
 

-26=2x 

-26/2=x 

x=-13

3x-7=5x+19
Add 7 to both sides.
3x=5x+26
Subtract 5x on both sides.
-2x=26
Divide by -2 on both sides.
x=-13


To check the answer you substitute x=-13 back into the equation.
3x-7=5x+19
3(-13)-7=5(-13)+19
-39-7=-65+19
-46=-46
