System of elimination

(8,6)

Step-by-step explanation:

Solve by elimination!

-2x-y=-22

2x-6y=-20

cross out, and merge!

-7y=-42

y = 6

Plugin y in one equation (I choose the easy one XD)

-2x-6=-22

-2x=-16

x = 8

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

your answer   is c
