determine the solution of the system. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

 

a) _ (type ordered pair)

b) there are infinitely many solutions

c) there are no solutions

Answer 1

I am assuming that the "elimination method" refers to manipulation of the equations to eliminate one variable (unknown).

 

Try multiplying each term of the first equation by 7.  Then you can add the 2 equations and eliminate the "y" term.  Now, you will be able to solve for "x".
