15

Пошаговое объяснение:

16.5-х+3.4=4.9

19.9-х=4.9

-х=4.9-19.9

-х=-15

Answer 3

To solve the equation 16.5 - (x + 3.4) = 4.9, we can follow these steps:

Step 1: Simplify the equation by removing parentheses. 16.5 - x - 3.4 = 4.9

Step 2: Combine like terms on the left side of the equation. 13.1 - x = 4.9

Step 3: To isolate the variable x, we can subtract 13.1 from both sides of the equation.

• x = 4.9 - 13.1

Simplifying further:

• x = -8.2

Step 4: Solve for x by multiplying both sides of the equation by -1 (or multiplying by -1 can also be considered as taking the negative of both sides). x = -1 * (-8.2)

Simplifying further: x = 8.2

Therefore, the solution to the equation 16.5 - (x + 3.4) = 4.9 is x = 8.2.
