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.
