Question

1)2х=4(х-28) 2)2(х+28)=4 3)2х=4(х+28)

Answer 1

1) 2x=4(x-28)
2x=4x -112
2x-4x= -112
-2x= -122
x=56
2)2(x+28)=4
x+28=2
x=2 -28
x= -26
3)2x=4(x+28)
2x=4x+112
2x -4x=112
- 2x=112
x= -56

Answer 2

1)2x=4(x-28).
2x=4x-112
2x-4x=-112
-2x=-112
x=-112:(-2)
X=56.
2)2(x+28)=4
2x+56=4
2x=4-56
2x=-52
X=-52:2
x=-26
3)2x=4(x+28)
2x=4x+112
-2x=112
X=112:(-2)
X=-56

Answer 3

Let's solve each of these equations one by one:

1. 2х = 4(х - 28)

Expand the right side of the equation: 2х = 4х - 112

Now, let's isolate x on one side of the equation. To do this, we'll move the terms containing x to the left side and the constant term to the right side: 2х - 4х = -112

Combine like terms: -2х = -112

Finally, divide both sides by -2 to solve for x: x = -112 / -2 x = 56

So the solution for this equation is x = 56.

2. 2(х + 28) = 4

First, distribute the 2 on the left side of the equation: 2х + 56 = 4

Now, let's isolate x on one side of the equation. Move the constant term to the right side: 2х = 4 - 56

Combine like terms: 2х = -52

Finally, divide both sides by 2 to solve for x: x = -52 / 2 x = -26

So the solution for this equation is x = -26.

3. 2х = 4(х + 28)

Expand the right side of the equation: 2х = 4х + 112

Now, let's isolate x on one side of the equation. Move the terms containing x to the left side and the constant term to the right side: 2х - 4х = 112

Combine like terms: -2х = 112

Finally, divide both sides by -2 to solve for x: x = 112 / -2 x = -56

So the solution for this equation is x = -56.
