Answer:2x + 4

Step-by-step explanation:

if you divide two linear binomials, you will get a quotient that is a monomial with a remainder.  Use long division.

 

 

 

               2/3

            ___________

(3x - 7) |  2x + 4

              2x - (14/3)

             ___________

                    (14/3) + 4

 

 

Quotient is  2/3

 

Remainder =  (14/3) + (12/3) = 26/3

 

 

To check, we multiply the quotient by the divisor, then add the remainder to the result.

 

 

(2/3)(3x - 7) + (26/3) =

 

2x - (14/3) + (26/3) =

 

2x + (12/3) =
