Me solve the problem with step by step
1/3x=-x+4

1/3x=-x+4

Move -x to the other side.

Sign changes from -x to +x.

1/3x+x=-x+x+4

1/3x+x=4

Find the common denominator for x which is 3. Pretend that x is 1/1x

Multiply by 3 for 1/1x

1(3)/1(3)x=3/3x

1/3x+3/3x=4

4/3x=4

Multiply by 3/4 for both sides.

4/3(3/4)x=4(3/4)

Cross out 4 and 3, divide by 4 and 3 then becomes x

Cross out 4 and 4 , divide by 4 and then becomes 3

x=3

x=3

step-by-step explanation:

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.
