Question

-2+x=5; 5+x=-1; -2+x=5

Answer 1

-2+х=5
х=7

5+х=-1
х=-6

-2+х=5
х=7

Answer 2

x=5+2=7

x=1-5=-4

x=5+2=7

Answer 3

Let's solve each of these equations step by step:

1. -2 + x = 5: To solve for x, we need to isolate it on one side of the equation. We can do this by performing inverse operations. Since -2 is being added to x, we can subtract -2 from both sides to eliminate it from the left side:

-2 + x - (-2) = 5 - (-2) x = 7

So the solution for the first equation is x = 7.

2. 5 + x = -1: Similarly, to solve for x, we want to isolate it on one side. In this case, we need to get rid of the constant term 5 on the left side. We can do this by subtracting 5 from both sides:

5 + x - 5 = -1 - 5 x = -6

The solution for the second equation is x = -6.

3. -2 + x = 5 (same as the first equation): Since this is the same equation as the first one, the solution remains the same:

x = 7

So, the solution for the third equation is also x = 7.

To summarize:

1. x = 7
2. x = -6
3. x = 7
