Question

3-4(2x-5)=2-6x срочно надо

Answer 1

3-8х+20=2-6х
-8х+6х=2-3-20
-2х=-21
х=10,5

Answer 2

В левой части раскрываем скобки:
3-8x+20=2-6x
Переносим все в левую часть:
3-8x+20-2+6x=0
Приводим подобные:
-2x+21=0
x=-21/(-2)
x=10.5

Answer 3

Solving the Equation 3-4(2x-5)=2-6x

To solve the equation 3-4(2x-5)=2-6x, we can follow these steps:

1. Distribute the -4 to both terms inside the parentheses on the left side of the equation. 2. Combine like terms. 3. Solve for x.

Step 1: Distribute the -4

The equation 3-4(2x-5)=2-6x becomes: 3 - 8x + 20 = 2 - 6x

Step 2: Combine Like Terms

Combine the constants on the left side of the equation: 23 - 8x = 2 - 6x

Step 3: Solve for x

Subtract 2 from both sides: 21 - 8x = -6x

Subtract -8x from both sides: 21 = 2x

Divide by 2: x = 10.5

So, the solution to the equation 3-4(2x-5)=2-6x is x = 10.5.
