How to do 2x+4=12 plz show how you got it

2x + 4 = 12

We're simply just trying to isolate x.

So, we must get x onto it's own side of the equal sign :)

Our first step is to subtract 4 from both sides.

2x + 4 - 4 = 12 - 4

Simplify.

2x = 8

Then, we divide both sides by 2.

2x ÷ 2 = 8 ÷ 2 

Simplify.

x = 4



To check your work, simply plug in the value of x into x in the original equation.

In this problem, x = 4, so plug in 4 for x.

2x + 4 = 12

2(4) + 4 = 12

Simplify.

8 + 4 = 12

12 = 12

Therefore, x = 4

Option B: is the correct option

Explanation:

The coordinates of the triangle ABC are A(-6,10), B(-7,7) and C(-4,6)

The co-ordinates of the image triangle A'B'C' are A'(2,7), B'(1,4) and C'(4,3)

To determine the translation rule, we can see from the figure that the image is translated right and down.

The translation is given by:

We can see from Point A to A',

To determine the value of c, we have,

   

     

Thus, from point B to B',

Solving c, we have,

Also for point C to C',

Solving for c, we have,

Thus, from all the above three points, the value of c is 3.

Hence, the translation is given by

Hence, Option B is the correct answer.
