Step 1) Combine like terms/variables.
7y and -2y are similar, combine them.
7+(-2y)=5y
3x has no similar variables, so it stays the same
3 and 6 are similar, without variables, combine them.
3+6=9
The final answer is 5y+3x+9

Answer:
7π
Step-by-step explanation:
SO first find the area of the whole circle
which has a radius of 3
a=πr^2
So 3^2=9
9π
Now the two circles which are the same in area due to having the same radius
so if you plug in the 1 for radius the answer would just be π or 1π
now multiply that by 2 becuase there are 2 identical circles
π*2=2π
Now subtract
9π-2π=7π
