abs(y^3 - 4) < 8*y
You could mean y/4 - 3, or you could possibly mean 4/y - 3. It is somewhat ambiguous which quotient you mean.
let x be one number and y be the other The first thing given is that x is 3 less than twice y so x=2y-3 and x+y=39 so x=39-y and substitute this into the first equation a 39-y=2y-3 42=3y y=14 and x=39-14 or 25 Answer x=25 and y=14 Now lets check it 25 is 3 less than 2x14 (YES) 14+25=39 (YES) Done
Here, y is a variable & it can take any value. If y = 3, then 5 is greater than y. If y = 5, then 5 is equal to y. If y = 99.123, then 5 is less than y. So, it all depends on the value of y.
x=3y-5 x+y=43 3y-5+y=43 2nd Number: 12 1st Number: 31
abs(y^3 - 4) < 8*y
y is 2 less than the product of 3 and x
It is not clear from the question whetherx is an even number, which is less than W orW minus an even number.The distinction obviously affects the possible answers.

3+y-17 simplifies to y-14
--------------- x+y=10 x-y=4 => x=y+4 ...=>y=3 =>x=7 The answer can be either 37 or 73 but since it should be less than 40... => The answer is 37. ---------------
4x-3 ----------- There is no specific answer to this question other than "another number" as the number in the question is unspecified. We could use algebra to represent this by, for example, calling the new value y and the original number x and saying that y = 4x - 3 (as above). We can not solve for y without knowing x here.
x = 4z/5 y = .72z 5x/4 = z By subsitution, we have: .9x = y Thus, x is 10% more than y, and Without Loss of Generality, y is 10% less than x.
y-7 would be the expression
In mathematical terms, a number x is less than y if y - x is positive.
