(k/5+3)*6=48 56/(36/k-2)=8

Question

(k/5+3)*6=48 56/(36/k-2)=8

Answer 1

(к/5+3)*6=48

к/5*6+3*6=48

к/5*6+18=48

к/5*6=48-18

к/5*6=30

к/5=30:6

к/5=5

к=5*5

К=25

 

56:(36/к-2)=8

36/к-2=56:8

36/к-2=7

36/к=7+2

36/к=9

к=36:9

К=4

 

 

Answer 2

6к/5+18=48

6к/5=48-18

6к/5=30

6к=30*5

6к=150

к=150/6

к=25

 

36/к-2=56/8

36/к-2=7

36=7*(к-2)

36=7к-14

36+14=7к

50=7к

50/7=к

7,1=к
