x - 15 < 35
x < 50
4x - 15 = 5x - 10 5x = 4x - 5 x = -5
'5' & '15' are odd numbers less than 20 , and are also multiples of '5'.

0, for example.
3x - 6 < 9 So, 3x < 15 Therefore, x < 5
4x - 15 = 5x - 10 5x = 4x - 5 x = -5
15 less than 7 times a number is:15-7n
That means that the sum of the number's factors, less than the number itself, is less than the number in question - in this case, if you add the factors of 15 (except 15 itself, which is also a factor of 15), you get a total that is less than 15.
No, however there are even numbers less than 15. An even number is any number that can be divided by two evenly, so it can be greater than 15 too.
x² - 15
The phrase can be expressed mathematically as: ( 2x - 6 < -36 ). To solve for ( x ), first add 6 to both sides, resulting in ( 2x < -30 ). Then, divide by 2 to find ( x < -15 ). Therefore, the quantity of the number must be less than -15.

It is: 15-5 = 10
