Question

Help me fast lol this is a biology related question.

Answer 1

A=5

B=9

C=3

D=4

Step-by-step explanation:

3+2=A, so A must equal 5.

A+4=B, since we know A equals 5 then 5+4=B, therefore B must equal 9.

2+C=5, then use algebra to solve by subtracting 2 from both sides. C=3.

3+1=D, so D must equal 4.
