      3(x+2)=5(2x+1)


      3x  +  6  =  10x  +  5  >  cancel out the 3x on the left by subtracting on both sides. 


                                              cancel out the 5 on the right by subtracting on both sides


      3x - 3x  +  6 - 5  =  10x - 3x  +  5 - 5


                             1      =   7x


                             7             7


      x  =  1/7

          3(x+2) = 5(2x+1) distribute


          3x+6 = 10x +5 subtract 5 on both sides


          3x+1=6x divide by 3x


          1=2x


          x=1/2

              x is not multiply
              x is an exponent
