Shape A is congruent to Shape B because If you were to rotate one of the two and flip it the would like up and match.
Multiply 2nd equation by 3 and add to first

It is neccesary because you cannot subtract them without having a common denominator so you have to rename 4 1/2
Our objective is to isolate n one side of the equation. The steps are as follows...
a=m-n
(Add n to both sides)
a+n=m-n+n
(The -n and +n cancel out, on the right side of the equation)
a+n=m
(Now subtract a from both sides)
a+n-a=m+a
(The +a and -a cancel out, on the right side of the equation)
n=m+a
