Hi there! I am guessing that you are looking for the value of "a"!

Here we go :

2(a + 3) = -12

distribute the 2 to the entire parentheses

2 × a = 2a

2 × 3 = 6

2a + 6 = -12

subtract 6 on each side of the equation

2a = -18

divide both side of the equation by 2

a = -9

There you go! I really hope this helped, if there's anything just let me know! :)

First you divide by two from both sides of equation form.

And it gave us ⇒ [tex]\frac{2(a+3)}{2}= \frac{-12}{2}[/tex].

Then simplify.

And it gave us ⇒ [tex]\frac{2(a+3)}{2}=a+3[/tex], [tex]\frac{-12}{2}=-6[/tex], and [tex]a+3=-6[/tex].

Next, subtract by three from both sides of equation form.

And it gave us ⇒ [tex]a+3-3=-6-3[/tex].

Finally, simplify.

And it gave us ⇒ [tex]a=-9[/tex]

Final answer: ⇒ [tex]\boxed{a=-9}[/tex]

Hope this helps!
