If (x+28y)/x=50 then what does (y+28x)/y=

17

Step-by-step 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

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
