The difference of two numbers is 16 and the sum of their squares is 130. What are the numbers.
Korvikt [17]
x - y = 16
x^2 + x^2 = 130

----------------
x^2 - y^2 = 256
+(x^2 + y^2 = 130)
2x^2 = 386
x^2 = 193
x = <span>13.892 (3DP)
----
</span>x - y = 16
13.892 - y = 16
-y = 2.108
y = -2.108
The numbers are: 13.892 and -2.108

What is 14=9-x I am trying to solve it
prisoha [69]
14 = 9 - x

First, subtract 9 from both sides.

14 - 9 = (9 - 9) - x
5 = -x

Now divide both sides by -1.
5/-1 = -1/-1x
-5 = x

The answer is x = -5.
