Which answer best describes the solution to the equation 5z + 4 = 4 + 5z? A. one solution B. no solution C. an infinite number of solutions D. z = 20

pooja195 (pooja195):

We are isolating z

pooja195 (pooja195):

Start by subtrcting 4 from both sides

OpenStudy (alurahenderson):

-1

pooja195 (pooja195):

4-4 is not -1

pooja195 (pooja195):

Your solution would be 0=0 so what would the answer be?

pooja195 (pooja195):

REMEBER when all the numbers are the same they will cancel out.

OpenStudy (alurahenderson):

Sorry I was subtracting from the 5 and I accidentally put a negative sign so 0

pooja195 (pooja195):

OpenStudy (alurahenderson):

0

pooja195 (pooja195):

Ok but how many solutions?

OpenStudy (alurahenderson):

One?

OpenStudy (anonymous):

bye

pooja195 (pooja195):

hmmm no 0=0

pooja195 (pooja195):

this means that any number we plug in place of x we will get 0=0

OpenStudy (alurahenderson):

Oh I put 0 earlier

OpenStudy (alurahenderson):

Thank you!

pooja195 (pooja195):

Thats right but this would mean there are infinte solutions :)

OpenStudy (alurahenderson):

Oh so it's C

pooja195 (pooja195):
