Need fast in solving the following equation

Option C: x=-9

Step-by-step explanation:

Given that:

-5(x+6)= 15

Multiplying -5 into the bracket:

-5x-30 = 15    ( "-" sign multiplied by "+" gives "-" )

-5x=15+30

-5x=45

Dividing both sides by -5 we get

x = -9

I Hope it will help you!

C

Step-by-step explanation:

First you do -5 times X, which gives you -5X.

Then you do -5 times positive 6, which gives you -30.

You'd have an equation like : -5X - 30 = 15.

Then you have to get rid of whatever's not connected to the X, which would be the 30. So to get rid of a negative number (since it has a subtraction in front of it, it would be negative) you'd have to add it to the other side of the equation. So you'd add 30 to the negative 30, eliminating the 30 altogether, and then you'd add 30 to the 15, resulting in 45. Which would have the equation as -5X = 45. To get rid of the -5 in front of the X, you'd have to divide both sides of the equation by -5. 45/-5 results in the answer of X = -9

x= 149. 24+7=31. 180-31=149
