Answer 1

6-3x+4-7+2x=0

3-x=0

х=3.

Ответ: 3.

Answer 2

6-3х+4=7-2х;

-3х+2х=7-10;

-х=- 3;

х=3...

Answer 3

Let's solve the equation step by step:

1. Distribute the number outside the parentheses: 3 * 2 - 3 * x + 4 = 7 - 2x

2. Combine like terms on each side of the equation: 6 - 3x + 4 = 7 - 2x

3. Combine the constants on the left side: 10 - 3x = 7 - 2x

4. To isolate the variable (x) on one side of the equation, we need to move the term with x to one side and the constant term to the other side. Let's move the -3x term to the right side by adding 3x to both sides:

   10 - 3x + 3x = 7 - 2x + 3x

   The -3x and +3x on the left side cancel each other out, leaving:

   10 = 7 + x

5. Now, let's isolate x by moving the constant term to the other side. To do this, subtract 7 from both sides:

   10 - 7 = x

   3 = x

So, the solution to the equation is x = 3.
