Answer 1

Option a is correct....odd prime

b = 12

c = -8

a = 8

Answer 2

$\huge\mathfrak\red{Here's\:Your\:Answer}$

Given that a=8

So solving 1st EQ.

a=b+10

8= b+10

or -b = -2

or b= 2

Now solving 2nd EQ

b+20 = c+40

or

2+20 = c+40

or c+40 = 22

or c = -18

Now solving 3rd EQ we get..

c+51

-18+51 = 33

Thus we get Option A (Odd Prime)
