Question

!х! - 11 =4 -5,2 + !x! = -2

Answer 1

Ответ:

х-11=4. -5,2+х=-2

х=11+4. х= -5,2+-2

х=15. х=3,2

15-11=4. -5,2+3,2=-2

4=4. -2=-2

Answer 2

It seems like you're trying to solve a system of equations. Let's break it down step by step.

The given equations are:

1. !x! - 11 = 4 - 5.2
2. !x! = -2

First, we can simplify equation 1:

!x! - 11 = -1.2

Now, add 11 to both sides of the equation to isolate !x!:

!x! = -1.2 + 11 !x! = 9.8

So, the solution to equation 2 is !x! = 9.8.

Now, let's check if this value satisfies equation 1:

!x! - 11 = -1.2

Since !x! is equal to 9.8, we can substitute it into the equation:

9.8 - 11 = -1.2

Now, subtract 11 from 9.8:

-1.2 = -1.2

The equation is satisfied, which means the solution for !x! is indeed 9.8, and it satisfies both equations.
