**Solve for Nye**

From first equation:

A + A + B = 8

Subtracting 2A from both sides â€”> B = 8 – 2A

From second equation:

C – B = 5

adding B to both sides â€”> C = 5 + B

Combining these two solutions:

â€”> C = 5 + (8 – 2A)

â€”> C = 13 – 2A

From third equation:

A + 2(C) = 11

substituting our solution for C in terms of A

â€”> A + 2(13 – 2A) = 11

â€”> A + 26 – 4A = 11

subtracting 26 from both sides and collecting the A terms

â€”> -3A = -15

dividing both sides by -3

â€”> A = 5

B = 8 – 2A

substituting A = 5

â€”> B = 8 – 2(5)

â€”> B = 8 – 10

â€”> B = -2

C = 13 – 2A

substituting A = 5

â€”> C = 13 – 2(5)

â€”> C = 13 – 10

â€”> C = 3

Therefore, final equation is:

A – B – 2(C) = ?

5 – (-2) – 2(3) = ?

5 + 2 – 6 = **1**

**Solve for Sagan**

From third equation:

**A = B + 2**

Substituting into second equation:

(B+2) + B – C = -7

adding 7 to both sides â€”> B + 2 + B – C + 7 = 0

adding C to both sides â€”> B + 2 + B + 7 = C

collecting terms â€”> **C = 2B + 9**

Now we can put A and C into the first equation:

(B+2) + (B x (2B+9)) = -10

multiplying the second term â€”> (B+2) + (2B^2 +9B) = -10

collecting terms â€”> 2B^2 + 10B + 2 = -10

adding 10 to both sides â€”> 2B^2 + 10B + 12 = 0

dividing all terms by 2 â€”> **B^2 + 5B + 6 = 0**

Using the quadratic equation where the solution to any equation ax^2 + bx + c = 0 is:

x = [-b +/- sqrt(b^2 – 4ac)] / 2a

In our equation â€”> a = 1, b = 5, c = 6

Therefore:

B = [-5 +/- sqrt(5×5 – 4×6)] / 2

â€”> B = [-5 +/- sqrt(25 – 24)] / 2

â€”> B = [-5 +/- sqrt(1)] / 2

â€”> B = [-5 +/- 1] / 2

â€”> **B = (-3, -2) two answers**

With this answer for B, we go back to A = B + 2 â€”> **A = (-1, 0)**

C = 2B + 9 â€”> **C = (3, 5)**

Our final equation then has the following two answers:

(A x B) + (2 x C) = ?

When A = -1, B = -3, C = 3, then the answer is â€”> (-1 x -3) + (2 x 3) = **9**

When A = 0, B = -2, C = 5, then the answer is â€”> (0 x -2) + (2 x 5) = **10**
