5x+130=8x+151

subtract 5x from each side

5x-5x+130=8x-5x+151

130 = 3x+151

subtract 151 from each side

130-151 =3x

-21 = 3x

divide by 3

-21/3 = 3x/3

-7 =x

5x+130=8x+151

-5x          - 5x        subtract 5x from both sides

   130  = 3x  + 151

  -151           -151     subtract 151 from both sides

    -21   = 3x  

      /3      /3       divide 3 by both sides

        -7  = x
