3 , 642 − 2 х ) ÷ 0 , 06 + 2 , 3 = 45 х=

To find the value of x in the given expression, we will follow these steps:

Step 1: Evaluate the expression inside the parentheses first: 3,642 - 2x

Step 2: Divide the result by 0.06: (3,642 - 2x) / 0.06

Step 3: Add 2.3 to the result from Step 2: (3,642 - 2x) / 0.06 + 2.3

Given that the final result is equal to 45, we can set up the equation as follows: (3,642 - 2x) / 0.06 + 2.3 = 45

Now, let's solve for x:

(3,642 - 2x) / 0.06 + 2.3 = 45 (3,642 - 2x) / 0.06 = 45 - 2.3 (3,642 - 2x) / 0.06 = 42.7 3,642 - 2x = 0.06 * 42.7 3,642 - 2x = 2,562 -2x = 2,562 - 3,642 -2x = -1,080 x = -1,080 / -2 x = 540

Therefore, the value of x in the given expression is 540.
