Question

1 – 5(1,5 + х) = 6 – 7,5х

Answer 1

Ответ:

1-5(1,5+x)=6-7,5x

1-7,5-5x=6-7,5x

-6,5-5x=6-7,5x

-5x+7,5x=6+6,5

2,5x=12,5

x=12,5/2,5

x=5

Answer 2

Let's solve the equation step by step:

1 - 5(1.5 + x) = 6 - 7.5x

First, let's simplify the equation by performing the multiplication:

1 - 7.5 - 5x = 6 - 7.5x

Next, combine like terms:

-6.5 - 5x = 6 - 7.5x

Let's isolate the terms with x on one side of the equation. We can do this by adding 7.5x to both sides:

-6.5 - 5x + 7.5x = 6 - 7.5x + 7.5x

Simplifying further:

2.5x - 6.5 = 6

Next, let's isolate the term with x by adding 6.5 to both sides:

2.5x - 6.5 + 6.5 = 6 + 6.5

Simplifying further:

2.5x = 12.5

To solve for x, divide both sides by 2.5:

(2.5x)/2.5 = 12.5/2.5

Simplifying further:

x = 5

Therefore, the solution to the equation 1 - 5(1.5 + x) = 6 - 7.5x is x = 5.
