Question

6×(2,3x-1)-3,5x+0,7x=0,5(x-14)

Answer 1

Ответ:

Объяснение:

13,8x-6-3,5x+0,7x=0,5x-7

13,8x-3,5x+0,7x-0,5x=-7+6

10,5x=-1

x=-1/10,5

Answer 2

To solve the equation, let's simplify and solve step by step:

6 × (2.3x - 1) - 3.5x + 0.7x = 0.5(x - 14)

First, let's simplify the expression on the left side:

13.8x - 6 - 3.5x + 0.7x = 0.5x - 7

Now, let's combine like terms on both sides:

(13.8x - 3.5x + 0.7x) - 6 = 0.5x - 7

Simplifying further:

(13.8x - 2.8x) - 6 = 0.5x - 7

11x - 6 = 0.5x - 7

Next, let's isolate the x terms on one side by adding 0.5x to both sides:

11x - 0.5x - 6 = -7

Combining like terms:

10.5x - 6 = -7

Now, let's isolate the constant term on one side by adding 6 to both sides:

10.5x - 6 + 6 = -7 + 6

Simplifying:

10.5x = -1

Finally, to find the value of x, divide both sides by 10.5:

x = -1 / 10.5

Simplifying further:

x ≈ -0.09524

Therefore, the approximate solution to the equation is x ≈ -0.09524.
