Answer:
x and y = 4
Step-by-step explanation:
Since y=x ---> x=2x-4
-x -x
0=x-4
+4 +4 ------------------> Therefore, x= 4 and y= y
If you could graph both lines you would find they intersect at (4,4)
The given identity tells you ...
.. (sum of numbers) * (sum of squares - product) = (sum of cubes)
Substituting the given information, you have
.. (sum of numbers) * (29 -10) = 133
Then you can divide by (29 -10) to get
.. sum of numbers = 133/19 = 7
The sum of the two numbers is 7.
