Use the elimination method to solve the system of equations.

Question

a+8b=3

a+2b=-3

Select the correct choice below and if a is the correct choice write out the answer and simplify your answer and write an ordered pair again only if a is the correct answer.

(a) There is one solution it is?

(b) There are infinitely solutions.

(c) There is no solution.

Answer 1

From the above we can see a=3-8b=-3-2b.

Thus 6=6b

b=1

By pluging in b, we see a=-5
