Answer 2

Ответ:

1) 13+28х=5х+17+23х

28х-5х-23х=17-13

х=корней не имеет

Пошаговое объяснение:

2)5-3х+4=17х+9-20х

-3х-17х+20х=9-5-4

уравнение корней не имеет

т. к х=0,на 0делить нельзя

Answer 3

To solve these linear equations, you'll want to isolate the variable x in each equation. Here's how you can do that:

1. 13 + 28x = 5x + 17 + 23x

First, simplify the equation by combining like terms:

28x - 23x - 5x = 17 - 13

Now, solve for x:

(28x - 23x - 5x) = (17 - 13)

0x = 4

Since 0 times any number is always 0, this equation has no solution. It means there is no value of x that will satisfy this equation.

2. 5 - 3x + 4 = 17x + 9 - 20x

First, simplify the equation by combining like terms:

(5 + 4) - 3x = (17x - 20x) + 9

9 - 3x = -3x + 9

Now, add 3x to both sides of the equation to isolate the x terms on one side:

9 - 3x + 3x = -3x + 3x + 9

9 = 9

This equation simplifies to 9 = 9. This equation is always true, which means it has infinitely many solutions. In other words, any value of x will satisfy this equation.

So, the solution to the second equation is that it's an identity, and it holds true for all real numbers of x.
