Perimeter of a rectangle is 15x+17y if the length is 7/2x+7y then find the width of the rectangle

The perimeter of a rectangle is given by the formula,

We substitute,

and

into the above formula to obtain the expression,

We now group the x and y terms on the Left Hand Side of the equation to get.

We now divide through by 2 to get,

Therefore the width of the rectangle is

step-by-step explanation:

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.
