X+2y=1
5-3y=3
Thank you anyway for this answer

 x = -1/3

y = 2/3

Step-by-step explanation:

5 -3y = 3 subtract 5 from both sides

-3y = 3 -5

-3y = -2  Divide both sides by -3

y = 2/3  Substitute for y in the first equation and solve for x

x + 2(2/3) = 1

x + 4/3 = 1  Change 1 to 3/3 and subtract 4/3 from both sides

x = 3/3 - 4/3

x = -1/3

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.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
