Question

-5(2-2x)=3(x-3)-5. 2x-4(x+7)=3(2-х)

Answer 1

-5(2-2x)=3(x-3)-5
-10+10х=3х-9-5
10х-3х=-9-5+10
7х=-4
Х=-4/7

2x-4(x+7)=3(2-х)
2х-4х-28=6-3х
2х-4х+3х=6+28
Х=34

Answer 2

Let's solve the equations step by step.

1. -5(2-2x) = 3(x-3) - 5

Let's simplify the equation:

-10 + 10x = 3x - 9 - 5

Combine like terms:

10x + 10 = 3x - 14

Move all the terms with x to one side and the constant terms to the other side:

10x - 3x = -14 - 10

7x = -24

Divide both sides by 7 to solve for x:

x = -24/7

So the solution to the first equation is x = -24/7.

2. 2x - 4(x+7) = 3(2-x)

Let's simplify the equation:

2x - 4x - 28 = 6 - 3x

Combine like terms:

-2x - 28 = 6 - 3x

Move all the terms with x to one side and the constant terms to the other side:

-2x + 3x = 6 + 28

x = 34

So the solution to the second equation is x = 34.

To summarize:

1. The solution to the equation -5(2-2x) = 3(x-3) - 5 is x = -24/7.
2. The solution to the equation 2x - 4(x+7) = 3(2-x) is x = 34.
