-3x = -12
Divide both sides by -3.
x=4

Step-by-step explanation:
Harsh is part of a school cricket team, and he has scored an average of 46 runs in 5 innings. His scores in 4 of them are 46,45, 39, and 55. His fifth score is calculated as follows:
Since he made 5 innings and has an average of 46, the total scores will be:
= 46 × 5
= 230
Total of his first 4 scores will be:
= 46 + 45 + 39 + 55
= 185
5th score = 230 - 185
= 45

Well... Basically, you should prove this by SSS property(side-side-side). It's fair to say that the length of a side is equal to itself so The line that cuts through the rectangle is a side for both rectangles. Thus because of the given, all the sides of the triangles are equal to one another. This is a very important trick for geometry(I remember using it a lot).
Hope this helps!
