Question

-2(2-5x)=2(x-3)-5 решить уравнение

Answer 1

-4+10х=2х-6-5

10х-2х=4-6-5

8х=-2-5

8х=-7

х=-7/8

Answer 2

To solve the equation, we'll first simplify both sides and then isolate the variable (x). Let's go step by step:

1. Start by distributing the negative sign on the left side: -2(2 - 5x) = -4 + 10x

2. Now, distribute the 2 on the right side: 2(x - 3) = 2x - 6

Now, the equation becomes: -4 + 10x = 2x - 6

3. Next, let's isolate the x variable on one side of the equation. To do this, we'll move all the x terms to one side and constants to the other side:

Subtract 2x from both sides: -4 + 10x - 2x = -6

Combine the x terms: 8x - 4 = -6

4. Now, isolate the constant term by adding 4 to both sides: 8x - 4 + 4 = -6 + 4

Simplify: 8x = -2

5. Finally, solve for x by dividing both sides by 8: x = -2 / 8

Simplify the fraction: x = -1/4

So, the solution to the equation is x = -1/4.
