Question

A.20/x =10
B.2y+4(y-15)=20

Answer 1

A. ) 20/x = 10
           x = 20/10
           x  = 2
b.) 2y + 4y - 60 = 20
       6y = 20+ 60
         y = 80 /6
         y = 13,33

Answer 2

A. 20/X = 10
 = 20/10 = X
 = 2 = X
 X = 2
B.2Y + 4 (Y-15 ) = 20
  2y - y ( 4 + 15 ) =20
  y(4 + 15 )= 20
 y = 20/4 + 15 = 20
