Question

1) 2,1 - 3,8; 2) Решите уравнение: 1) x+19=12 2) -25 - x = -17

Answer 1

1) = -1,7
1) x= 12-19; x= -7
2) -x=-17+25; -x=8; x=-8

Answer 2

1)-7,5
2)
1) х+19=12
х=12-19
х = -7
2) -25 - х = -17
-х= -17+25
-х=8
х= -8

Answer 3

1. To solve the equations:
2. x + 19 = 12

To isolate the variable x, we need to get rid of the constant term on the left side of the equation. We can do this by subtracting 19 from both sides:

x + 19 - 19 = 12 - 19

Simplifying, we have:

x = -7

So the solution to the equation is x = -7.

2. -25 - x = -17

To isolate the variable x, we can start by adding x to both sides of the equation:

-25 - x + x = -17 + x

Simplifying, we have:

-25 = -17 + x

Next, we can subtract -17 from both sides of the equation:

-25 - (-17) = -17 + x - (-17)

Simplifying, we have:

-25 + 17 = x

-8 = x

So the solution to the equation is x = -8.

Therefore, the solutions to the given equations are:

1. x = -7
2. x = -8
