Question

СРООООООЧНОООО 2) 13-(2x-5)=x-34) 26-(17-2x)=5x​

Answer 1

2)

$13 - (2x - 5) = x - 3$

$13 - 2x + 5 = x - 3$

$-2x - x = - 3 - 5 - 13$

$- 3x = - 21$

$x = \frac{ - 21}{ - 3}$

$x = \frac{21}{3}$

$x = 7$

Ответ:

$x = 7$

4)

$26 - (17 - 2x) = 5x$

$26 - 17 + 2x = 5x$

$- 3x = - 9$

$x = \frac{ - 9}{ - 3}$

$x = 3$

Ответ:

$x = 3$

Answer 2

To solve the equations, let's work on them one by one:

1. 13 - (2x - 5) = x - 3

To simplify the equation, let's start by removing the parentheses:

13 - 2x + 5 = x - 3

Combine like terms:

18 - 2x = x - 3

Now, let's isolate the x terms on one side and the constant terms on the other side:

-2x - x = -3 - 18

-3x = -21

Divide both sides of the equation by -3:

x = (-21) / (-3) = 7

Therefore, the solution to the first equation is x = 7.

2. 26 - (17 - 2x) = 5x

Again, let's remove the parentheses:

26 - 17 + 2x = 5x

Combine like terms:

9 + 2x = 5x

Next, isolate the x terms on one side and the constant terms on the other side:

2x - 5x = -9

-3x = -9

Divide both sides of the equation by -3:

x = (-9) / (-3) = 3

Thus, the solution to the second equation is x = 3.

In summary, the solutions to the given equations are:

1. x = 7
2. x = 3
