Question

Х−1,15=3,4+(2,3–1,4).

Answer 1

х−1,15=3,4+(2,3–1,4).

х-1,15=3,4+1,3-1,4

х-1,15=4,3

х=4,3+1,15

х=5,45

Answer 2

To solve the equation, let's first perform the operations step by step:

1. Subtract 1.15 from both sides of the equation:

   H - 1.15 = 3.4 + (2.3 - 1.4)

2. Perform the subtraction inside the parentheses:

   H - 1.15 = 3.4 + 0.9

3. Add 3.4 and 0.9:

   H - 1.15 = 4.3

4. Now, to find the value of H, add 1.15 to both sides of the equation:

   H = 4.3 + 1.15

5. Calculate the sum:

   H = 5.45

So, the value of H is 5.45.
