5X10 = 50
102-50= 52
Answer = 52
N=25 because 20 divided by 4 is 5 which is 1/5 of n meaning 5x5 is 25
This is the same as any math problem you may have solved before.
First, start by isolating the x on one side. I will choose to keep the coefficient positive, so I will add x to both sides.
6>2x+2
Subtract 2
4>2x
Divide by 2
2>x
Or
x<2
The answer would be 2.16.
This is because the two negatives would cancel each other out when multiplying. This would basically make the question

.
Now 3.3 is definitely not less than 2.4, so the answer would be 2.16
