Question

3)-8 + 2х = х - 5 4) 9 – 3х =1 + х 5) 6х – 7 = 8 + 3х

Answer 1

Ответ:

Пошаговое объяснение:

-8 + 2х = х - 5

2х - х = -5 + 8

х = 3

9 - 3х = 1 + х

-3х - х = 1 - 9

-4х = -8

х = -8 : (-4)

х = 2

6х - 7 = 8 + 3х

6х - 3х = 8 + 7

3х = 15

х = 15 : 3

х = 5

X=3 )))))))))))))))))))

Answer 3

To solve each of these linear equations for the variable x, you can perform the following steps:

3. -8 + 2x = x - 5

First, let's get all the x terms on one side of the equation and the constants on the other side:

-8 + 2x - x = -5

Combine like terms:

-8 + x = -5

Now, add 8 to both sides to isolate x:

x = -5 + 8

x = 3

So, the solution is x = 3.

4. 9 - 3x = 1 + x

First, let's get all the x terms on one side of the equation and the constants on the other side:

9 - 1 = 3x + x

Combine like terms:

8 = 4x

Now, divide both sides by 4 to isolate x:

8/4 = 4x/4

2 = x

So, the solution is x = 2.

5. 6x - 7 = 8 + 3x

First, let's get all the x terms on one side of the equation and the constants on the other side:

6x - 3x = 8 + 7

Combine like terms:

3x = 15

Now, divide both sides by 3 to isolate x:

3x/3 = 15/3

x = 5

So, the solution is x = 5.
