The difference between seven seven times a number and 8 8 is equal to four four times the sum of the number and 3 3. find the number. if x represents the number, which equation is correct for solving this problem?

20/3

7x - 8 = 4(x+ 3)

Step-by-step explanation:

Let the unknown number be x.

Now, the difference between 7 times a number and 8 is equal to four times the sum of the number and 3.

Writing this mathematically:

7x -8 = 4(x + 3)

To solve completely, we open the bracket:

7x - 8 = 4x + 12

7x - 4x = 12 + 8

3x = 20

x = 20/3

The correct equation to solving the problem is 7x - 8 = 4(x + 3)
