Answer:

x = -2

Explanation:

To solve for x in the equation - 3(x+5) = -9, we will follow the steps below:

First, we will start by opening the bracket

-3( x+ 5) = -9

-3x - 15 = -9

Next, is to add 15 to both-side of the equation

-3x - 15 + 15 = -9 + 15

-3x = 6

Divide both-side of the equation by -3


(-3X)/(-3) =
(6)/(-3)

(On the left-hand side of the equation, -3 at the numerator will cancel-out -3 at the denominator leaving us with just x, while on the right-hand side of the equation, 6 will be divided by -3)

x = -2
