3 plus four times a number.

3 + 4x

Step-by-step explanation:

Let "a number" be x.

Therefore "four times a number" is 4 multiplied by x which is 4x.

Now add 3 for "3 plus".

3 + 4x

Our equation would be: 3 + 4x.

Let's say x=8

That would now make our equation:

3 + 4(8) =

Step-by-step explanation:

But let's solve this equation :)

First, we would add 3+4, to get 7.

Then, we would multiply the 7 by 8.

Lastly, we know 7 x 8 = 56

So, 3+4(8)= 56

But we could also create a function statement out of this.

Our statement for this equation would be:

When x equals 8 the answer or in algebraic terms the "output" is 56.

Have a great day!!
