Question

-1,4(x-6)=7(4x-1)=11,8 как его решить?

Answer 1

Раскроем скобки: -1,4*х+8,4=28*x-7=11,8⇒7+8,4=(28+1,4)*x=11,8⇒15,4=11,8 - не верно!

Ответ: нет решений.

Answer 2

To solve the equation, we need to simplify and isolate the variable (x) on one side of the equation. However, there seems to be a typographical error in the equation you provided. It appears to be three separate equations rather than one single equation. I'll solve each equation individually:

1. -1 * 4(x - 6) = 7(4x - 1)
2. 7(4x - 1) = 11
3. 8 = 11 (this equation seems incorrect as it contradicts 8 being equal to 11)

Let's start with the first equation:

1. -1 * 4(x - 6) = 7(4x - 1)

Step 1: Distribute the -1 and 7 on the respective sides. -4x + 24 = 28x - 7

Step 2: Move the variable terms (containing x) to one side and the constant terms to the other side.

Subtract 28x from both sides: -4x - 28x + 24 = -7

Combine the x terms: -32x + 24 = -7

Step 3: Move the constant term to the other side by subtracting 24 from both sides:

-32x = -7 - 24 -32x = -31

Step 4: Isolate x by dividing both sides by -32:

x = -31 / -32

Simplify:

x = 31 / 32

So the solution to the first equation is: x = 31/32.

Now let's move on to the second equation:

2. 7(4x - 1) = 11

Step 1: Distribute 7 on the left side: 28x - 7 = 11

Step 2: Move the constant term to the other side by adding 7 to both sides:

28x = 11 + 7 28x = 18

Step 3: Isolate x by dividing both sides by 28:

x = 18 / 28

Simplify:

x = 9 / 14

So the solution to the second equation is: x = 9/14.

It seems that there was an error in the third equation you provided, as 8 cannot be equal to 11. If you meant a different equation or if there's any other question, feel free to let me know!
