Answer:

  yes

Step-by-step explanation:

The offered ordered pair is a solution if those x- and y-values satisfy both equations. Let's check:

  9x +y = 10

  9(1) +(1) = 9 +1 = 10 . . . . true

__

  6x +5y = 11

  6(1) +5(1) = 6 +5 = 11 . . . . true

__

The ordered pair (x, y) = (1, 1) satisfies both equations, so (1, 1) is a solution to this system.

1) Placing (1,1) in equation 9x + y = 10

[tex]:\implies\tt{9(1) + 1 = 10} \\ \\ :\implies\tt{9 + 1 = 10} \\ \\ :\implies\tt{10 = 10} \\ \\ :\implies\tt{lhs = rhs}[/tex]

2) Placing (1,1) in equation 6x + 5y = 11

[tex]:\implies\tt{6(1) + 5(1) = 11} \\ \\ :\implies\tt{6 + 5 = 11} \\ \\ :\implies\tt{11 = 11} \\ \\ :\implies\tt{lhs = rhs}[/tex]

  • Thus, the ordered pair (x,y) = (1.1) satisfies both the equations so it is solution to the given system.
