2(x−3)=5x+9,x=  ?2(x - 3) = 5x + 9,\quad x = \;?

Answer: −5-5

  1. Distribute the 2.

    2x−6=5x+92x - 6 = 5x + 9

  2. Move the x terms to one side and the constants to the other.

    −15=3x-15 = 3x

  3. Divide by 3.

    x=−5x = -5

  4. Check: both sides equal -16.

    2(−8)=−16=5(−5)+92(-8) = -16 = 5(-5) + 9

  5. So the answer is

    x=−5x = -5
