Question

1) 9,5x+2=5,7x-5,6;2)2,6(x-2)=1,8(x-4)

Answer 1

Ответ:

1)9,5х+2=5,7х-5,6

9,5х-5,7х= -5,6-2

3,8х= -7,6

Х= - 2

2)2,6(х-2)=1,8(х-4)

2,6х-5,2=1,8х-7,2

2,6х-1,8х= - 7,2+5,2

0,8х= - 2

Х= - 2,5

Answer 2

Ответ:

1) 9.5х + 2 = 5.7х - 5.6

9.5х-5.7х = -5.6 - 2

3.8х = -7.6

х = 7.6 : 3.8

х = 2

Ответ : 2

2) 2.6 (х-2) = 1.8 (х-4)

2.6х - 5.2 = 1.8х -7.2

2.6х -1.8х = -7.2 +5.2

0.8х = -2

х = 2:0.8

х = -2.5

ответ : -2.5

Answer 3

Let's solve the equations step by step:

1. 9.5x + 2 = 5.7x - 5.6

First, let's move all terms involving x to one side of the equation and constants to the other side:

9.5x - 5.7x = -5.6 - 2

Now, simplify the left side by subtracting 5.7x from 9.5x:

(9.5 - 5.7)x = -5.6 - 2

3.8x = -7.6

Now, divide both sides by 3.8 to isolate x:

x = (-7.6) / 3.8

x = -2

So, the solution to the first equation is x = -2.

2. 2.6(x - 2) = 1.8(x - 4)

First, distribute the constants on the left and right sides of the equation:

2.6x - 5.2 = 1.8x - 7.2

Now, move all terms involving x to one side of the equation and constants to the other side:

2.6x - 1.8x = -7.2 + 5.2

Combine like terms on both sides:

0.8x = -2.0

Now, divide both sides by 0.8 to isolate x:

x = (-2.0) / 0.8

x = -2.5

So, the solution to the second equation is x = -2.5.
