3-x
==> [ 3x - 8 ]
x-8>17
x-15, x represents the unknown number, and to have 15 less you would simply subtract 15 from x.... therefore your answer is x-15
write the number that is 100 less
x + x - 3 = 2x - 3
The answer is 1. 5 times x - x < 5 + x It has to be 1, anything over 1 could not be less than.
It depends on the unknown number.
4,312,800
It is a number eight less than zero.
Let the unknown number be x and so the expression is: 2x-3
twice an unknown number less one and one-half times the same number equals two ---- Let the unknown number be "x":: Equation: 2x - (3/2)x = 2
