Question

1) 6x-(x-1)=2(2x-4) 2) 3 (2x-5)=7x+11 3) 3(2x-5)=7x+1

Answer 1

1) 6х - (х - 1) = 2(2х - 4)

6х - х + 1 = 4х - 8

5х - 4х = - 8 - 1

х = - 9

- - - - - - - - - - - -

2) 3(2х - 5) = 7х + 11

6х - 15 = 7х + 11

6х - 7х = 11 + 15

- х = 26

х = - 26

- - - - - - - - - - - -

3) 3(2х - 5) = 7х + 1

6х - 15 = 7х + 1

6х - 7х = 1 + 15

- х = 16

х = - 16

Answer 2

1)6х-(х-1)=2(2х-4)

 6х-х+1=4Х-8

 5х+1=4х-8

 5х-4х=-8-1

 х=-9

2)3(2х-5)=7х+11

  6х-15=7х+11

  6х-7х=11+15

  -х=26

  х=-26

3)3(2х-5)=7х+1

  6х-15=7х+1

  6х=7х=1+15

  -х=16

  х=-16

Удачи тебе

Answer 3

Let's solve each of the equations step by step:

1. 6x - (x - 1) = 2(2x - 4)

To simplify the equation, let's distribute the 2 on the right side:

6x - x + 1 = 4x - 8

Combine like terms on both sides:

5x + 1 = 4x - 8

Now, isolate the x-term by subtracting 4x from both sides:

5x - 4x + 1 = -8

x + 1 = -8

Finally, isolate the x-term by subtracting 1 from both sides:

x = -8 - 1

x = -9

Therefore, the solution to the equation is x = -9.

2. 3(2x - 5) = 7x + 11

Let's distribute the 3 on the left side:

6x - 15 = 7x + 11

Next, let's isolate the x-term by subtracting 6x from both sides:

-15 = x + 11

Now, isolate the x-term by subtracting 11 from both sides:

-15 - 11 = x

-26 = x

So, the solution to the equation is x = -26.

3. 3(2x - 5) = 7x + 1

Distribute the 3 on the left side:

6x - 15 = 7x + 1

To isolate the x-term, subtract 6x from both sides:

-15 = x + 1

Next, subtract 1 from both sides:

-15 - 1 = x

-16 = x

Thus, the solution to the equation is x = -16.

To summarize:

1. x = -9
2. x = -26
3. x = -16
