Answer:
A1=59
A2=85
A3=49
A4=no.because strait lines add up to 180 and it does not
B1=x=133andy=133
B2=53,61,and 56
B3=x=37andy= 37
B4=x=54and y=68
C1=y= 43and x=51
a+b+c=-1
a=1
b=-1
c=-1
So for this u just replace the letters
not sure about x+y=7
For this case we convert the mixed numbers into fractions:

Rewriting the expression:

We simplify:

Thus, the simplified form is:
