The method of solving:
We say that X is Liams unknown number.
X*5-60=X
5X-60=X
5X-X=60
4X=60
4X/4=60/4
X=15

68 - 5x = 3*(x + 4) 68 - 5x = 3x + 12 56 = 8x x = 7
Multiply 105 by .6 (60%) because if one subtracts 40% of something he/she is left with 60% of the number. 105 (.6)= 63
A negative number squared equals a positive number. When multiplying, odd numbers of negatives result in a negative answer, and even numbers of negatives result in a positive answer.
9/1 18/2 27/3 endless possibilities... The result of any number multiplied by 9, then divided by the number equals 9 :-) Any number can be divided by 9 if its sum of digits can be divided by 9.
The number 5 times 10 times 10 equals 500. You can use any number you want. (But the result will not be 500 for any other number except 5.)
68 - 5x = 3*(x + 4) 68 - 5x = 3x + 12 56 = 8x x = 7

The result is a negative number in this case.

Yes, but only if the original number is zero or 1 .
If you divide that by 24, you get the number of days. If you then divide the result by 365, you get the number of years.If you divide that by 24, you get the number of days.

A comparator with two inputs A and B subtracts A from B and inspects the sign of the result: Y(A, B) := sign(A-B)
4 times a number added to 7 times the number equals 33
