7(x-1)<35
7x-7<35 (distrubute the 7 into the parrethases by multiplying)
7 +7 +7 (add 7 to 35)
42 (get 42)
7 = 6 (divide it by 7 and get answer)
its mostly about inverse operations which are when you see a multiplication you divide on the other side which in this case the indicator is the less than (like an equal sign)
