3q + 2z, although it could be 2*(3q+z)
Any number when doubled becomes even. Thus the key part of the question is identifying a 3 digit even number that you can add 2 to to become a 4 digit number. The answer is 998. Thus to find the original number we need to do 998/2. This calculates to 499.
So, to put your question in an algebraic expression, it should look something like this: X/2 = 2X - 3 Then you would just solve... X = 2(2X - 3) X = 4X - 6 -3X = -6 X = 2
The clue is the word 'doubled' . It means multiply the given number by '2' Hence 34 doubled = 34 x 2 = 68 Similarly ' The word 'tripled' means multiply by '3' Hence 24 x 3 = 72
Doubled # = original# * 2^(times it doubles)
The algebraic expression "twice a number z" can be represented as 2z. In this expression, the variable z represents the unknown number, and multiplying it by 2 gives you twice that number. This expression can be used in algebraic equations and formulas to represent scenarios where a number needs to be doubled.
3q + 2z, although it could be 2*(3q+z)
The quotient of a number and 2 is the same as the difference of the number doubled and 3.
When you double any number you are in-fact multiplying it by 2 which is an even number. All even numbers are multiples of 2. When a number is doubled, it is multiplied by 2 and so the result is always a multiple of 2. Thus it must always be an even number.

There is no such number, although I am struggling to prove it.

its an exponent it means squared or doubled because its a 2

51 x 2 = 102
Doubled # = original# * 2^(times it doubles)
(100 - 6)/2 = 47 The prime number 47 when doubled is six less than one hundred.
