I need help finding out what properties were used in this equation, 4(x+5)=9x+4x-34

Step-by-step explanation:

4(x+5)=9x+4x-34

4x + 4*5 = 9x + 4x - 34    {distributive property}

4x + 20 - 4x = 9x + 4x - 34 - 4x  {subtraction property of equality}

20 = 9x - 34  

20 + 34 = 9x - 34 + 34  {Addition property of equality}

54 = 9x

54/9 = 9x/9  {division property of equality}

6 = x

x = 6

whats the
