Answer:
14
Step-by-step explanation:
To answer this, we need to set up an equation. Let X represent this number. That would mean our equation would be (x-7)*8=4x. We can use the distributive property to make our equation 8x-56=4x. Subtract 4x on both sides. 4x-56=0. Add 56 to both sides. 4x=56. Divide by 4 on both sides. x=14. This means our mystery number is 14. I know this isn't one of the answer choices but if you check 14 it works.
Answer:
The correct answer is 14
Step-by-step explanation:
It is given that,8 times the difference between a number and 7 is equal to 4 times the number.
To find the number
From the above data we can write,
Let x be the number then,
8 * (x - 7 ) = 4x
8x - 56 = 4x
8x - 4x = 56
4x = 56
x = 56/4 = 14
Therefore the number is 14
