Question

Решите (10у-3.3):5.2+8.9=10

Answer 1

Ответ приблизительный
1,9у-0,6+8,9=10
1,9у=10+0,6-8,9
1,9у=1,7
у=1,7:1,9
у=0,8

Answer 2

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS):

1. Perform the division first: (10y - 3.3) / 5.2
2. Then add 8.9 to the result.

Now, let's proceed with the calculation:

Step 1: (10y - 3.3) / 5.2

Step 2: Divide each term by 5.2: 10y / 5.2 - 3.3 / 5.2

Step 3: Simplify: 1.923y - 0.635

Now, add 8.9 to the result:

Final step: 1.923y - 0.635 + 8.9

Now, there seems to be an error in your initial equation. It is missing an equal sign before "10." If the equation is meant to be equal to 10, then we have:

1.923y - 0.635 + 8.9 = 10

Now, let's solve for y:

1.923y + 8.9 = 10

Subtract 8.9 from both sides:

1.923y = 10 - 8.9 1.923y = 1.1

Now, divide both sides by 1.923 to isolate y:

y = 1.1 / 1.923 y ≈ 0.572

So, the solution to the equation is y ≈ 0.572.
