Answer:

x = -4

Step-by-step explanation:

First, add 7 to both sides:

7x - 7=  12x + 13

7x = 12x + 20

Subtract 12x from both sides:

-5x = 20

Divide each side by -5:

x = -4

So, the answer is x = -4

valkas [14]

Answer:

D) coordinates of its reflection image is ( -3 , 2) .

Step-by-step explanation:

Given : S ( 3 ,2)  If point S is reflected across the y-axis,

To find : what are the coordinates of its reflection image.  

Solution : We have given S ( 3 ,2).

By the reflection rule over y -axis : (x ,y) →→ ( -x , y) .

Then x = 3 , y = 2

Then coordinates of its reflection image is

(3 , 2 ) →→ ( -3 , 2) .

Therefore,  D) coordinates of its reflection image is ( -3 , 2) .
