Question

If x+y =10 and x-y =6 then what is value of x³_y³ ?

Answer 1

Answer:

Step-by-step explanation:

x+y=10

x-y=6

_____

2x=16            

x=16/2

x=8

Substituting the value of x

x+y=10

8+y=10

y=10-8  

y=2

_________________________

X^3-y^3

= 8^3 - 2^3

=512-8= 504

Answer 2

Step-by-step explanation:

if x+y=10 and x- y is equals to 6

then the value of x and y will be (8,2 )

so x³_y³= 8³_2³
