Step-by-step explanation:

given,

MP = x - 8

PN = 3x - 9

MN = 21

we know,

according to segment addition postulate AB + BC = AC

now,

MP + PN = MN

→ x - 8 + 3x - 9 = 21

→ 4x - 17 = 21

→ 4x = 21 + 17

→ 4x = 38

→ x = 38/4 = 9

→ x = 9

therefore, value of x is 9.

hope this answer helps you dear! take care

Help me here in this equation and tell me how to check it to know if solution is the answer

Leokris [45]

ok so first step is to get rid of x

than you want to subtract x from 4/5x

than you want to minus 7 from 9 and you get 2

now times 5 to both sides like like this

4/5x5 and 2x5=

4x=10

x=2.5

i hope this helps you

$\frac{4}{5} x \frac{5}{1} = \frac{4}{1} =4x$

then you have $2 x 5= 10$

so then you will have $4x=10\\10divide by 4 =\\2.5\\x=2.5$
