Question

10 + 10 + x ÷ 2 + x = 39​

Answer 1

Ответ:

х = 12 целых и ⅔

Пошаговое объяснение:

10 + 10 + х ÷ 2 + х = 39

20 + х ÷ 2 + х = 39

х ÷ 2 + х = 39 - 20 = 19

(½)х + х = 19

(3/2)х = 19

х = 19 ÷ (3/2)

х = 19 × (⅔)

х = (38/3) = 12 целых и ⅔

Answer 2

To solve for the value of x in the equation:

10 + 10 + x ÷ 2 + x = 39

You can follow these steps:

Step 1: Combine like terms on the left side of the equation.

10 + 10 is equal to 20, and x + x is equal to 2x. So the equation becomes:

20 + (2x ÷ 2) = 39

Step 2: Simplify further.

2x ÷ 2 simplifies to x. So the equation now looks like this:

20 + x = 39

Step 3: Isolate the variable x by subtracting 20 from both sides of the equation.

20 + x - 20 = 39 - 20

This simplifies to:

x = 19

So, the value of x that satisfies the equation is 19.
