Answer:
x = -2
Step-by-step 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
\(\frac{-3X}{-3}\) = \(\frac{6}{-3}\)
(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
