Question

The Sum of four times a number and four is forty-eight. Find the number.

Answer 1

You again? ok

4x+4=48

so you have to undo everything here

so first if this was a normal problem you would

1. multiply 4 and x

2.add 4

so go from the last step to the first like this

4x+4=48

-4. -4

--------------

4x=44

now hear to undo multiplication you would divide

4x/4=48/4

=

x=12

Answer 2

8

Explanation:

To find the value of the number, form an equation using the provided information.

Define variables used:

Let the number be n.

The sum of the number and 4 is equivalent to (n +4). Four times this sum would therefore by 4(n +4).

Let's equate it to 48:

4(n +4)= 48

Now that the equation is formed, let's solve for n.

Divide both sides by 4:

n +4= 48 ÷4

n +4= 12

Subtract 4 from both sides:

n= 12 -4

n= 8

Thus, the number is 8.
