The cellphones cost 8475 and 7525 respectively.

8475 + 7525 = 16000

Answer:

1st Brand = 7762.5 pesos

2nd Brand = 8237.5 pesos

Total = 16 000 pesos

Step-by-step explanation:

1st Brand = x (Mas maganda ito)

2nd Brand = x + 475 (Mas maganda ito)

or

1st Brand = x - 475 (Pwede naman sana ito pero mamamali tayo kapag sinubstitute na natin ang value of x)

2nd Brand = x (Pwede naman sana ito pero mamamali tayo kapag sinubstitute na natin ang value of x)          

How to find the value of x (Gawa-gawa ko lang po itong equation para mahanap ang value of x pero parang tama naman kapag isu-substitute):

x = (16000 - 475) / 2

x = (15525) / 2

x = 7762.5 pesos

Substitute:

1st Brand = x

                = 7762.5 pesos

2nd Brand = x + 475

                  = 7762.5 + 475

                  = 8237.5 pesos
