Question

(1,2х + 16,8)*(-13,1) = 0

Answer 1

1,2х+16,8=0:(-13,1)

1,2х+16,8=0

1,2х=0-16,8

1,2х=-16,8

Х=-16,8:1,2

Х=-14

Answer 2

To solve this problem, we need to perform multiplication of the two given numbers:

(1,2х + 16,8)*(-13,1)

To multiply two numbers in this format, we use the distributive property of multiplication:

a(b + c) = ab + ac

Using this property, we can write:

(1* -13,1) + (2х + 16,8) * (-13,1)

= -13,1 - 13,1х - 222,48

We have simplified the multiplication to get the final answer of -13,1 - 13,1х - 222,48 = 0.

Now we can solve for х:

-13,1х = 235,58

х = -18

Therefore, the value of х that makes the equation (1,2х + 16,8)*(-13,1) = 0 true is -18.
