Find the solution to the system of equations, x + 3y = 7 and 2x + 4y = 8. 1. Isolate x in the first equation: x = 7 − 3y 2. Substitute the value for x into the second equation: 2(7 − 3y) + 4y = 8 3. Solve for y: 14 − 6y + 4y = 8 14 − 2y = 8 −2y = −6 y = 3 4. Substitute y into either original equation: x = 7 − 3(3) 5. Write the solution as an ordered pair: ( , )

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.
