Question

10x + 2(4x - 5) =2x +10.

Answer 1

Ответ:

10x-2(4x-5)=2x+10

10х-8х+10=2х+10

10х-8х-2х=10-10

0х=0

х - любое число.

Answer 2

To solve the equation 10x + 2(4x - 5) = 2x + 10, you'll need to simplify and isolate the variable x. Here are the steps:

1. Distribute the 2 on the left side of the equation: 10x + 8x - 10 = 2x + 10

2. Combine like terms on both sides of the equation. Add or subtract the x terms and constants separately: (10x + 8x) - 10 = (2x + 10)

   18x - 10 = 2x + 10

3. To isolate the variable x on one side of the equation, you can start by moving the 2x from the right side to the left side. You can do this by subtracting 2x from both sides of the equation:

   18x - 2x - 10 = 10

4. Now, combine the x terms on the left side: 16x - 10 = 10

5. To get x by itself on one side, add 10 to both sides:

   16x - 10 + 10 = 10 + 10

   16x = 20

6. Finally, to solve for x, divide both sides by 16:

   (16x)/16 = 20/16

   x = 5/4

So, the solution to the equation is x = 5/4 or 1.25.
