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!

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
