Answer:

yes

Step-by-step explanation:

To determine if (1, 9) is a solution, substitute x = 1 into the right side of the equations and if the result is y = 9 then it is a solution

y = 1 + 8 = 9 ← True

y = 5(1) + 4 = 5 + 4 = 9 ← True

Thus (1, 9) is a solution to the system of equations.

Answer:Yes

Step-by-step: All you need to do is substitute the numbers so 9=1+8 = true

and 9=1 x 5 +4 = true so the answer is yes
