Question

find the value of x (please don't spam or I'll report)​

Answer 1

Answer:

This system of equation is of the form

a1x+b1y=c1

a2x+b2y=c2

where a1=1,b1=k+1,c1=5 

and a2=k+1,b2=9 and c2=8k−1

For infinitely many solutions, we must have

a2a1=b2b1=c2c1

The given system of equations will have infinite solutions, if

k+11=9k+1=8k−15

⇒k+11=9

Answer 2

Answer:

the value of x =150°

Step-by-step explanation:

complete angle=360°

x+46°+64°+100°=360°

x+210°=360°

x=360°-210°

x=150°
