Question

1/4 x y + y + 17,5 = 36,5

Answer 1

1/4 x y + y +21,5 = 36,5
5/4 x y = 15
y = 12

Answer 2

\(\left(\dfrac{1}{4}+1\right)y+17,5=36,5\)

\(\dfrac{5}{4}y=19\)

\(y=15,2\)

Answer 3

\(\dfrac{5}{4}\) x y = 9

y =\(9:\dfrac{5}{4}=7,25\)

Answer 4

1/4xy+y+17,5=36,5

1/4 x y x 2+ 17,5 =35,5

1/4 x y x2=35,5-17,5

1/4 x y x 2=18

y x 2= 18:1/4

yx2=72

y=72:2

y=36
