3 times X

Answer 1

3 times X= 3X

Because it is the same as 1X plus 1X plus 1X.

The X has an 'invisible' 1 in front of it....

Another example could be, What is 4 times X + 2?

It would equal 4X + 2, because when doing algebra you can only add things called 'like terms' so you can only add things like 2y+7y and 4yz+2yz or 4+3.

But you cannot add terms that are different, such as 2y+3z or 5+7x, they will just stay the same. So, 2y+3z=2y+3z and 5+7x=5+7x

However, you can MULTIPLY anything, so 2y times 3z= 6yz (2 times 3=6) and 5 times 7x= 35x and 4x times 3x= 12x2, this is because you have 2 xs!

So overall this is what you should know from all the above:

• You can multiply un-like terms! Even if the terms (eg. 2; 3x; 7y) are not the same.
• You cannot add or subtract un-like terms. You can only leave them as they are.
• When multiplying things like x or y or z remember to do your 'powers'

Examples:

1. MULTIPLYING UN-LIKE TERMS-

3n times 2m= 6mn (put letters in alphabetic order) or 5y times 4x= 20xy

2. ADDING/SUBTRACTING LIKE AND UN-LIKE TERMS-

You can add/subtract 7z+3z/ 7z-3z, = 10z/4z.

3. DOING POWERS-

x times x3= x4 because there is an 'invisible' 1 next to the first x.

And 3x2 times 4x3 = 12x6

Answer 2

Three times X can be represented as 3X, which is a multiplication operation where the number 3 is multiplied by the variable X. This can also be written as X + X + X, indicating that X is added to itself three times. In algebraic terms, the expression 3X simplifies to 3 times the value of X.

Answer 3

Well honey, 3 times X is just 3X. It's as simple as that, no need to overcomplicate things. Math may not be everyone's cup of tea, but this one is a piece of cake.
