Question

1. (x+26)-12=360 2. 7(x-15)=1841 3. ( 132-x) : 4=23 4. 910 : ( x+11) = 35

Answer 1

Ответ:

Я знаю только 3.

(132-x)+4=23

132-х 4 23

132-х=92

-х=92-132

-х=-40

Пошаговое объяснение:

(132-x)+4=23 Сократить дробь

132-х 4 23

Умножьте обе части

132-х=92

Answer 2

To solve these equations, you can follow these steps:

1. $x + 26 - 12 = 360$

   First, simplify the left side of the equation:

   $x + 14 = 360$

   Now, isolate $x$ by subtracting 14 from both sides:

   $x = 360 - 14$ $x = 346$

2. $7(x - 15) = 1841$

   Start by distributing the 7 on the left side:

   $7x - 105 = 1841$

   Next, add 105 to both sides:

   $7x = 1841 + 105$ $7x = 1946$

   Now, divide both sides by 7 to isolate (x:

   $x = \frac{1946}{7}$

3. $\frac{132 - x}{4} = 23$

   Start by multiplying both sides by 4 to get rid of the fraction:

   $132 - x = 4 \cdot 23$ $132 - x = 92$

   Now, isolate $x$ by subtracting 132 from both sides:

   $-x = 92 - 132$ $-x = -40$

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

   $x = 40$

4. $910 / (x + 11) = 35$

   Start by multiplying both sides by $x + 11$ to get rid of the fraction:

   $910 = 35(x + 11)$

   Now, distribute 35 on the right side:

   $910 = 35x + 385$

   Next, subtract 385 from both sides:

   $910 - 385 = 35x$ $525 = 35x$

   Finally, divide both sides by 35 to isolate (x:

   $x = \frac{525}{35}$ $x = 15$
