it is 75
Unfortunately, as in a very large number of cases, the above answer, from The WikiAnswers® Community is wrong.
3 x 35 = 105 On the number line ... -2,-1,0,1,2,3.....103,104,105,106,107,......
3x = 35 ??? 3x = 35 x = 35/3 ------------- ( about 11 and 7/10 )
Well, isn't that an interesting little math puzzle we have here? To find two numbers that multiply together to give you -105, we can think of numbers like 15 and -7. When you multiply 15 by -7, you get -105. Just remember, math is like a beautiful painting - sometimes you just need to mix the right colors together to create something wonderful.
