If x increased by the product of 11 and y is 103, and 9x increased by the product of 10 and y is 126, what are the values of x and y?

A. x = 8y=5

B. x = 9. y = 12

C. X = 4, y = 9

D. x = 9, y = 4

C. x=4, y=9

Step-by-step explanation:

The given information show that

x+11y=103 (1)

9x+10y=126 (2)

Isolate x from (1)

x=103-11y

Substitute x=103-11y into (2)

9 (103-11y) + 10y=126

927-99y+10y=126

-89y=-801

y=9

So x=103-11x9=4
