Answer 1

Ответ:

Пошаговое объяснение:

16-6х=3х-38

16+38=9х

54=9х

х=54\9=6

 2(3х-10)=7(х-12)

6х-20=7х-84

-х=-64

х=64

24(х-9)=48

24х-216=48

24х=264

х=264\24=11

9000(30x-26)=36000

30х-26=36000\9000

30х-26=4

30х=30

х=1

Answer 2

16-6х=3х-38

9х=54

х=6

Ответ:6

2(3х-10)=7(х-12)

6х-20=7х-84

-х=-64

х=64

Ответ:64

24(х-9)=48

24х-216=48

24х=264

х=11

Ответ:11

9000(30х-26)=36000

270000х-234000=36000

270000х=270000

Answer 3

Let's solve each equation step by step:

1. $16 - 6x = 3x - 38$

First, let's simplify the equation by moving like terms to the same side:

Add $6x$ to both sides:

$16 - 6x + 6x = 3x - 38 + 6x$

This simplifies to:

$16 = 9x - 38$

Now, add $38$ to both sides:

$16 + 38 = 9x - 38 + 38$

$54 = 9x$

To isolate $x$, divide both sides by $9$:

$x = \frac{54}{9}$

$x = 6$

2. $2(3x - 10) = 7(x - 12)$

Let's distribute the numbers on the left and right sides of the equation:

$2 \cdot 3x - 2 \cdot 10 = 7 \cdot x - 7 \cdot 12$

This simplifies to:

$6x - 20 = 7x - 84$

Now, let's isolate $x$. First, move the $6x$ term to the right side by subtracting $6x$ from both sides:

$-20 = x - 84$

Now, add $84$ to both sides:

$-20 + 84 = x - 84 + 84$

$64 = x$

3. $24(x - 9) = 48$

Divide both sides by 24:

$\frac{24(x - 9)}{24} = \frac{48}{24}$

This simplifies to:

$x - 9 = 2$

Now, add 9 to both sides:

$x - 9 + 9 = 2 + 9$

$x = 11$

4. $9000(30x - 26) = 36000$

Divide both sides by 9000:

$\frac{9000(30x - 26)}{9000} = \frac{36000}{9000}$

This simplifies to:

$30x - 26 = 4$

Now, add 26 to both sides:

$30x - 26 + 26 = 4 + 26$

$30x = 30$

Finally, divide both sides by 30:

$\frac{30x}{30} = \frac{30}{30}$

This simplifies to:

$x = 1$

So, the solutions to the equations are:

1. $x = 6$
2. $x = 64$
3. $x = 11$
4. $x = 1$
