What is the justification for the step taken from line 2 to line 3?

5 lines of math. the first line has, 3 x plus 9 minus 7 x equals x plus 10 plus x. the second line has, negative 4 x plus 9 equals 2 x plus 10. an arrow pointing from the front of the second line to the front of the third line. the third line has, negative 6 x plus 9 equals 10. the fourth line has, negative 6 x equals 1. the last line has x equals negative startfraction 1 over 6 endfraction.

what is the question here

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
