Answer:

7(x+4)-2/3 (x-6) < 2[x-3(x+5)]

Do it 1 step at a time.

7(x+4)-2/3 (x-6) < 2[x-3x-15]

7x+28 - 2/3 (x-6) < 2[x-3x-15]

I'll assume you mean (2/3)*x-6)

---

7x+28 - (2x/3) - 4 < 2[-2x-15]

7x+24 - (2x/3) < -4x-30

Add 4x

11x+24 - (2x/3) < -30

Add 30

11x + 54 - (2x/3) < 0

Multiply thru by 3

33x + 162 - 2x < 0

31x < 162

x < 162/31
