Question

3,9 : (х+0,13)=-2,6​

Answer 1

$3,9:(x+0,13)=-2,6\\\\x+0,13=3,9:(-2,6)\\\\x+0,13=-1,5\\\\x=-1,5-0,13\\\\x=-1,63$

Проверка:

$3,9:(-1,63+0,13)=-2,6\\\\3,9:(-1,5)=-2,6\\\\-2,6=-2,6$

Answer 2

It looks like you have a linear equation with a variable 'x'. To solve for 'x' in this equation, you can follow these steps:

1. Start by isolating 'x' on one side of the equation. In this case, you want to get 'x' on its own on the left side of the equation.

2. First, let's move the 0.13 to the other side of the equation by subtracting it from both sides:

   3.9 / (-2.6) = x

3. Now, calculate the division on the left side of the equation:

   -1.5 = x

So, the solution to the equation is:

x = -1.5

Therefore, the value of 'x' is -1.5.
