63x + 28y = -6

Select the correct choice below and fill in any answer boxes present in your choice.

A.The solution is __ ​(Type an ordered​ pair.)
B.There are infinitely many solutions.
C.There is no solution.

Answer 1

C. No solution

Explanation:

Eliminate the y terms by multiplying by 28 and 4

28(-9x-4y=1)

4(63x+28y=-6)

This forms

-252x-112y=28

252x+112y=-24----------------------add the y terms to eliminate them

-252x+252x=28+-24

0=4--------------------------x terms also eliminated

No solution
