Find a number such that 7 times the number is 56 greater than the opposite of the number.

pls. i don't get it..

4

Step-by-step explanation:

The opposite of a number is its negative. For example, the opposite of 3 would be -3.

Equipped with that information, we just need to find a number that is halve of 56, since if it stays the same except that its opposite, it will be 56 away.

Draw a number line. This can be a great help in problems like these.

If we divide 56 by 2, we get 28. Now the opposite of 28 is -28.

What happens if we add 56 to -28? We get positive 28.

Now that we know the number, we need to find out what number to multiply 7 by to get that.

The simple way to do this is to divide 28 by 7.

28/7=4.

7*4=28.

The answer is 4.

Hope this helps!

the discriminant is 64 + 4*1*12 = 112

this is prime.
