Answer:
Yes
Step-by-step explanation:
(x, y) = (1, 2)
substitute x and y to the equation to see if the right hand side of the equation is equally to the left hand side
I) 4x + y = 6
4 × (1) + 2 = 6
6 = 6 ( Correct)
II) 8x + 5y = 18
8 × (1) + 5 × (2) = 18
18 = 18 (Correct)
(1, 2) satisfies both equation, hence the answer is yes
