Question

Solve. −3(x+5)=−9 Enter your answer in the box.

Answer 1

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

Answer 2

-3x-15=-9
+15 +15
-3x=6
/-3 /-3

x=-2
