Question

12-2x = 3x - 4(x - 5) ​

Answer 1

Відповідь: 12-2x=3x-4(x-5)

12-2x=3x-4x+20

-2x-3x+4x=20-12

-x=8

x=8/(-1)

x= -8

________

12-(2*(-8))=3*(-8)-4(-8-5)

Answer 2

To solve the equation 12 - 2x = 3x - 4(x - 5), we will first simplify the equation by applying the distributive property.

12 - 2x = 3x - 4x + 20

Next, combine like terms:

12 - 2x = -x + 20

To isolate the variable x, we need to move the terms with x to one side of the equation. Let's move the terms with x to the left side:

-2x + x = 20 - 12

Simplifying further:

-x = 8

To solve for x, we multiply both sides of the equation by -1 to get rid of the negative sign:

x = -8

Therefore, the solution to the equation 12 - 2x = 3x - 4(x - 5) is x = -8.
