Question

-20-1,7x=48,9+3,6x x=?

Answer 1

Ответ:

-20-1,7x = 48,9+3,6x

-1.7x-3.6x = 48.9 + 20

-5.3x = 68.9

x = -13

Answer 2

To solve for x in the equation -20 - 1.7x = 48.9 + 3.6x, you can follow these steps:

1. First, let's move all terms involving x to one side of the equation and constants to the other side. To do this, add 1.7x to both sides and subtract 48.9 from both sides:

-20 - 1.7x + 1.7x = 48.9 + 3.6x + 1.7x

This simplifies to:

-20 = 48.9 + 5.3x

2. Now, isolate the variable x. To do this, subtract 48.9 from both sides:

-20 - 48.9 = 48.9 - 48.9 + 5.3x

-68.9 = 5.3x

3. Finally, divide both sides by 5.3 to solve for x:

(-68.9) / 5.3 = (5.3x) / 5.3

x ≈ -12.98

So, the solution for x is approximately -12.98.
