Question

−0,2k=20 k+m=−9 k= m=

Answer 1

k= -100

m=91

надеюсь помогла,оцени,пожалуйста,лучшим ответом)

Answer 2

Ответ:

к=-100

m=91

Объяснение:

-0,2к=20 /(-0,2) - избавляемся от (-0,2) в неизвестном К, деля обе стороны на (-0,2) ⇒

к=-100

-100+m=-9 (сразу подставляем найденные (-100 ) к К)

m=-9+100 (известные к известным - неизвестные к неизвестным)

m=91

Проверка

-0,2·(-100)=20

-100+91=-9

Answer 3

It looks like you've provided a system of equations:

1. -0.2k = 20
2. k + m = -9
3. k = m

Let's solve this system step by step:

Equation 1:
-0.2k = 20

Divide both sides by -0.2: k = 20 / -0.2
k = -100

Equation 2:
k + m = -9

Since we know k = -100 from Equation 1: -100 + m = -9

Add 100 to both sides: m = -9 + 100
m = 91

Equation 3:
k = m

From Equation 3, you've already established that k and m are equal.

So, in this system of equations, the solutions are: k = -100 m = 91
