Question

3 3/10 -х=2 7/10Решите пожалуйста!!!!!

Answer 1

-х=2 7/10-3 3/10
-х=27/10-33/10
-х=-6/10
х=3/5

Answer 2

To solve for x in the equation:

3 3/10 - x = 2 7/10

First, we need to get x by itself on one side of the equation.

We can start by subtracting 2 7/10 from both sides of the equation:

3 3/10 - x - 2 7/10 = 0

To simplify the left side, we need to find a common denominator for 3/10 and 7/10. The least common multiple of 10 and 10 is 10.

3/10 = 3/10 x 1/1 = 3/10 x 1/1 x 10/10 = 30/100

7/10 = 7/10 x 1/1 = 7/10 x 1/1 x 10/10 = 70/100

So, the equation becomes:

30/100 - x - 70/100 = 0

Simplifying further:

-40/100 - x = 0

-40/100 is the same as -4/10, which reduces to -2/5.

So, the equation becomes:

-2/5 - x = 0

To solve for x, we can add 2/5 to both sides of the equation:

-2/5 + 2/5 - x = 0 + 2/5

-x = 2/5

Finally, we can solve for x by multiplying both sides by -1:

x = -2/5

Therefore, the solution to the equation is:

x = -2/5
