Answer 1

3х = 28 - х // + х

4х = 28 // :4

х = 7

Answer 2

Ответ: 3х=28-х

3х+х=28

4х=28                 28:4=7

х=7

Answer 3

To solve the equation 3x = 28 - x, we need to isolate the variable x on one side of the equation. Here's how we can do it step by step:

Step 1: Combine like terms

On the right side of the equation, we have 28 - x. To combine like terms, we can rewrite it as -x + 28.

Step 2: Add x to both sides

To eliminate the -x term on the right side, we can add x to both sides of the equation. This gives us:

3x + x = -x + 28 + x

Simplifying this equation, we get:

4x = 28

Step 3: Divide by 4

To isolate x, we can divide both sides of the equation by 4:

(4x)/4 = 28/4

Simplifying further, we have:

x = 7

Therefore, the solution to the equation 3x = 28 - x is x = 7.
