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

kolezko [41]

We conclude that the solution to the given linear equation is x = 15/13.

<h3>How to solve that equation for x?</h3>

Here we have the linear equation:

13x - 4 = 11

And we want to solve this for x. To do so, we need to isolate x in one side of the equation.

We can start by adding 4 in both sides, so we get:

13x - 4 + 4 = 11 + 4

13x = 15

Now we can divide both sides by 13, so we get:

13x/3 = 15/13

x = 15/13

We conclude that the solution to the given linear equation is x = 15/13.
