Question

8/9-x=11/15 хочу понять

Answer 1

8/9-x=11/15
1) в начале переносим 8/9
-х=11/15 - 8/9
теперь приводим эти 2 дроби к общему знаменателю
2) домножаем дробь 11/15 на 3, а дробь 8/9 на 5
получается:
-х= 33/45-40/45
-x=-7/45
теперь избавляемся от минусов
получается:
х=7/45

Answer 2

Х = 8/9 - 11/5
х= 40/45 -99/45 (привели к общ.знаменателю)
х=-59/45

Answer 3

To solve the equation 8/9 - x = 11/15, we can follow these steps:

Step 1: Simplify the equation

To simplify the equation, we can find a common denominator for the fractions on both sides. The least common multiple (LCM) of 9 and 15 is 45. Multiplying both sides of the equation by 45 will eliminate the denominators.

(8/9) * 45 - x * 45 = (11/15) * 45

Step 2: Solve for x

Now we can solve for x by simplifying the equation further.

40 - 45x = 33

Step 3: Isolate x

To isolate x, we need to move the constant term to the other side of the equation.

-45x = 33 - 40

Step 4: Simplify

Simplifying the equation further:

-45x = -7

Step 5: Solve for x

To solve for x, divide both sides of the equation by -45.

x = -7 / -45

Simplifying the division:

x = 7/45

Therefore, the solution to the equation 8/9 - x = 11/15 is x = 7/45.

Please note that the solution provided is based on the given equation and the steps followed to solve it.
