Answer:
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)

Division is one of the four fundamental arithmetic operations. The length of each fabric piece is 0.3 yards.
<h3>What is Division?</h3>
The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Darlene has 3/5 a yard of fabric, which he cuts into 2 equal pieces. Therefore, the length of each fabric piece can be found by dividing the length of the entire fabric by 2.
Length of a fabric piece
= Length of total fabric that Darlene has / 2
= (3/5) yards / 2
= 3/(5×2) yards
= 3/10 yards
= 0.3 yards
Hence, the length of each fabric piece is 0.3 yards.
