Will the sum of two linear expressions each with an x-term , always, sometimes, or never have an x-term ? explain your reasoning

The sum will have an x-term sumtimes ... whenever
the x-terms alone don't add up to zero.

Examples:

-- Two linear expressions:

         y +  x
and   
         y + 2x

The sum of the x-terms alone is (x + 2x) = 3x .
So the sum of the expressions has an x-term.

         (y + x) + (y + 2x)  =  2y + 3x .


Two different linear expressions:

       y + 3x
and
       y - 3x

The sum of the x-terms alone is (3x - 3x) = zero.
So the sum of the expressions doesn't have an x-term.

         (y + 3x) + (y - 3x)  =  2y .

7days is 168 hours in decimal form it is just 168 there is no decimal form for this because it is like 168.0 and there is no number you are dividing it by for it to be a decimal.hope this
