Answer:

Step-by-step explanation:
See Attachment for Complete Question
From the attachment, we can see that F is plotted at

On the x axis, G is 3 units to the left;
And on the y axis, G is 2 units above
So, the coordinates of G is calculated as:


Hence:
<em>G is plotted at (2,6)</em>
Step 1: Create Equation: 12+15+x=55
Step 2: Solve it: you will get x=28
Step 3: You could check it by plugging your answer in.
Hope that helps!!!
