Answer 1

Ответ:

Пошаговое объяснение:

4x-5,6=3x-2,7

4х-3х=5.6-2.7

х=2.9

-50-17x=15x-14

-17х-15х=50-14

-32х=36

х=36:(-32)

х=-1 1\8

12x-19=13x​

12х-13х=19

-х=19

х=-19

Answer 2

Ответ:

Пошаговое объяснение:

4х-5.6=3х-2.7

4х-5.6+2.7=3х

5.6-2.7=х

х=2.9

-50-17х=15х-14

15х+17х=-50+14

32х=-36

х=-8/9

12х-19=13х

х=-19

Answer 3

To solve the given equations, let's take them one by one:

Equation 1: 4x - 5,6 = 3x - 2,7

It seems there is a comma in the equation, which could be a decimal point. Assuming that, let's rewrite the equation:

4x - 5.6 = 3x - 2.7

To solve for x, we want to isolate the variable x on one side of the equation. We can do this by subtracting 3x from both sides:

4x - 3x - 5.6 = -2.7

Combining like terms:

x - 5.6 = -2.7

Next, let's isolate x by adding 5.6 to both sides:

x - 5.6 + 5.6 = -2.7 + 5.6

Simplifying:

x = 2.9

So the solution for Equation 1 is x = 2.9.

Equation 2: -50 - 17x = 15x - 14

To solve this equation, we want to isolate the variable x. Let's start by adding 17x to both sides:

-50 - 17x + 17x = 15x - 14 + 17x

Simplifying:

-50 = 32x - 14

Next, let's isolate the term with x by adding 14 to both sides:

-50 + 14 = 32x - 14 + 14

Simplifying:

-36 = 32x

To solve for x, divide both sides by 32:

-36/32 = 32x/32

Simplifying:

-9/8 = x

So the solution for Equation 2 is x = -9/8.

Equation 3: 12x - 19 = 13x

To solve this equation, let's isolate the variable x by subtracting 13x from both sides:

12x - 13x - 19 = 13x - 13x

Simplifying:

-x - 19 = 0

To solve for x, let's multiply both sides by -1 to change the sign:

(-1)(-x - 19) = (-1)(0)

Simplifying:

x + 19 = 0

Next, let's isolate x by subtracting 19 from both sides:

x + 19 - 19 = 0 - 19

Simplifying:

x = -19

So the solution for Equation 3 is x = -19.

Summary: Equation 1: x = 2.9 Equation 2: x = -9/8 Equation 3: x = -19
