Which statement best describes a solution to the system of equations 3x+y=17 x+2y=49 a. it has no solution b. it has infinite solutions c. it has a single solution x=15 y=17 d. it has a single solution x=-3 y=26

  It has a single solution x=-3 y=26

Step-by-step explanation:

The ratios of coefficients of x and y are different, so the pair of equations has one solution. It is easy to tell the first offered solution (15, 17) does not satisfy the first equation, so that choice is eliminated.

Fortunately, the second offered solution, (x, y) = (-3, 26), satisfies both equations.

The equations have a single solution: (x, y) = (-3, 26).
