Answer:

x=5

Step-by-step explanation:

The sum of the angles of a quadrilateral is 360

L+M+J+K =360

75+ 96+14x+5 +114 = 360

Combine like terms

290 +14x = 360

Subtract 290 from each side

290-290 +14x= 360-290

14x = 70

Divide by 14

14x/14 = 70/14

x = 5

PLEASE HELP ASAP I WILL GIVE BRAINSLET TO THE CORRECT ANSWER!!!!!!!!!!

<u>Answer</u>:

Therefore has one solution.

<u>explanation</u>:

Given equations:

6x + y = -7

-24x -7y = 25

Make y the subject:

6x + y = -7

y = -7 - 6x ..............equation 1

-24x -7y = 25

-7y = 25 + 24x

y = (25 + 24x)/-7 ..........equation 2

Solve them simultaneously:

(25 + 24x)/-7 = -7 - 6x

25 + 24x = -7 (-7 - 6x)

25 + 24x = 49 + 42x

42x - 24x = 25- 42

18x = -24

x = $-\frac{4}{3}$

Then y is:

y = -7 - 6x

y = -7 - 6( $-\frac{4}{3}$ )

y = 1

Has one separate value of x and y: ( $-\frac{4}{3}$ , 1 ); so it has one solution.
