Question

Answer 1

17

Explanation:

(x+28y)/x =50

Multiply each side by x

(x+28y)/x *x =50*x

x+28y = 50x

Subtract x

x-x+28y = 50x-x

28y = 49x

Divide by y

28y/y = 49x/y

28 = 49 x/y

Divide by 49

28/49 = x/y

We want to find

(y+28x)/y

Rewriting as

y/y +28 (x/y)

1 + 28(x/y)

Replacing x/y with (28/49)

1 + 28(28/49)

1 +28*28/49

1+784/49

1+16
