23 and 32 {(32+23=55) (32-23=9)}

Difference is 9: x-y=9

From the second equation x=9+y (substitute that into the first equation to solve for y).

9+y+y=55

so, 2y= 55-9

2y=46

y= 46/2

y=23. (Substitute that back into the second equation to find x.)

x=9+y = 23+9 = 32.

23+32 = 55 (Check).

Hope the solution helped.

How do I solve this?
Tju [1.3M]

Answer:  A:  3x^2y^(3/2)

Step-by-step explanation:

This can be written as

(81*x^8*y^6)^(1/4)

Then multiply each exponent by (1/4):

81^(1/4)*x^(8(1/4))y^6(1/4))

81^(1/4) = 3

x^(8(1/4)) = x^2

y^6(1/4)) = y^(3/2)

The result:  3x^2y^(3/2)
