Question

(3,12-x)×3,7 = 6,919​

Answer 1

3,12-x=6,919÷3,7

3,12-x=1,87

-x=1,87-3,12

x=1,25

Answer 2

It seems like you're trying to perform a multiplication operation, but your notation is a bit unclear. Let's break it down step by step.

You have two sets of numbers enclosed in parentheses:

1. (3, 12-x)
2. (3, 7)

To multiply these sets together, you would typically use the distributive property. This means you multiply each element in the first set by each element in the second set and then sum the products. Let's do the calculation:

(3, 12-x) × (3, 7) = (3 * 3, 3 * 7, (12-x) * 3, (12-x) * 7)

Now, let's compute each of these products:

1. 3 * 3 = 9
2. 3 * 7 = 21
3. (12-x) * 3 = 36 - 3x
4. (12-x) * 7 = 84 - 7x

So, the result of the multiplication is:

(3, 12-x) × (3, 7) = (9, 21, 36-3x, 84-7x)

If you meant something different by your notation or have specific values for "x," please provide more context, and I'll be happy to assist further.
