Answer 2

Ответ:

17

Пошаговое объяснение:

2x-4=30

2x=30+4

2x=34

x=17

Answer 3

To solve the equation 2x - 4 = 30, you want to find the value of x.

First, isolate the variable x by performing the following steps:

1. Add 4 to both sides of the equation to eliminate the constant term on the left side: 2x - 4 + 4 = 30 + 4 2x = 34

2. Now, to solve for x, divide both sides by 2: 2x / 2 = 34 / 2 x = 17

So, the correct answer is 17 (Б).
