Answer 2

Ответ:

3х = 16-х      12=12

Пошаговое объяснение:

3х = 16-х    если х=8, то 3 · 8=16 - 8

24≠8

3х = 16-х  если х=12, то 3 · 12=16-12

38≠4

3х = 16-х   если х=20, то 3 · 20=16-20

60≠ -4

3х = 16-х  если х=4, то 3 · 4  = 16-4

12=12

Answer 3

To solve the equation 3x = 16 - x, we need to isolate the variable x on one side of the equation. Let's solve it step by step:

Starting equation: 3x = 16 - x

First, let's simplify the right side of the equation: 3x = 16 - x Add x to both sides: 3x + x = 16 - x + x Combine like terms: 4x = 16

Now, we'll isolate x by dividing both sides of the equation by 4: 4x = 16 Divide by 4: (4x)/4 = 16/4 x = 4

Therefore, the solution to the equation 3x = 16 - x is x = 4. None of the provided answer options (8, 12, 20, 4) are correct.
