9x+2=3x-10

3(x-2)=-2(x+3)



Sagot :

 9x + 2 = 3x - 10
-3x        -3x        
 6x + 2 = -10
        -2     -2
       6x = -12
        6       6
         x = -2

3(x - 2) = -2(x + 3)
3(x) - 3(2) = -2(x) - 2(3)
3x - 6 = -2x - 6
+2x      +2x       
5x - 6 = -6
     +6    +6
      5x = 0
       5     5
       x = 0
