jaiden worked out his homework problem below. choose the statement that best describes his work.
solve for x in the diagram below.
step 1: 3x-8=2x+23
step 2: x-8=23
step 3: x=31

The
solve for x does mean, finding the value of x
as we see in the figure, the first step to find such a value is equalizing 3x-8 to 
2x+23, that is possible because the right angle was bisected by a line, so the value of each angle must be equal.
to find x, 3x-8 = 2x+23 , equivalent to 3x  -  2x =23 +8 = 31
x =31°
finally 
the steps are true, 1, 2 and 3
