Question

[х-4]=2 [у+5]=3 [3+х]=1,5 [7-у]=-2

Answer 1

Х-4=2 или х-4=-2
х=6 х=2

у+5=3 или у+5=-3
у=8 у=2

3+х=1,5 или 3+х= -1,5
х= -2,5 х= -4,5

7-у=-2 или 7-у=2
-у= -9 -у= -5
у=9 у=5

Answer 3

Looks like you've provided a system of equations with variables x and y. I'll help you solve it step by step.

The given equations are:

1. |x - 4| = 2
2. |y + 5| = 3
3. 3 + x = 1.5
4. 7 - y = -2

Let's solve them one by one:

Equation 1: |x - 4| = 2

We have two cases to consider: a) x - 4 = 2 b) x - 4 = -2

Solving for x in each case: a) x = 2 + 4 = 6 b) x = -2 + 4 = 2

So, we have two possible solutions for x: x = 6 or x = 2.

Equation 2: |y + 5| = 3

Similarly, two cases: a) y + 5 = 3 b) y + 5 = -3

Solving for y in each case: a) y = 3 - 5 = -2 b) y = -3 - 5 = -8

Two possible solutions for y: y = -2 or y = -8.

Equation 3: 3 + x = 1.5

Solving for x: x = 1.5 - 3 = -1.5

Equation 4: 7 - y = -2

Solving for y: y = 7 + 2 = 9

Now, let's summarize the solutions we found:

1. x = 6, y = -2
2. x = 2, y = -8
3. x = -1.5, y = 9

These are the solutions to the system of equations you provided.
