Perimeter of a rectangle is 15x+17y if the length is 7/2x+7y then find the width of the rectangle
bogdanovich [222]

The perimeter of a rectangle is given by the formula,


P=2l+2w


We substitute,


P=15x+17y


and


l=\frac{7}{2}x+7y


into the above formula to obtain the expression,




15x+17y=2(\frac{7}{2}x+7y)+2w



15x+17y=7x+14y+2w




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


15x-7x+17y-14y=2w




8x+7y=2w



We now divide through by 2 to get,



4x+\frac{7}{2}y=w



Therefore the width of the rectangle is


4x+\frac{7}{2}y

What is the solution of the system?
Kryger [21]
Greetings!

Solve the System, using Elimination:
\left \{ {{4x+2y=18} \atop {2x+3y=15}} \right.

Multiply Equation #2 by 2:
\left \{ {{4x+2y=18} \atop {2(2x+3y)=2(15)}} \right.

\left \{ {{4x+2y=18} \atop {4x+6y=30}} \right.

Eliminate variable x:
-\frac{ \left \{ {{4x+2y=18} \atop {4x+6y=30}} \right.}{0x-4y=-12}

4y=-12

Divide both sides by 4:
\frac{4y}{4}= \frac{12}{4}

y=3

Input this value into one of the Equations: 
4x+2y=18

4x+2(3)=18

Simplify:
4x+6=18

(4x+6)+(-6)=(18)+(-6)

4x=12

Divide both sides by 4.
\frac{4x}{4}= \frac{12}{4}

x=3

The Solution to this System (The Point of Intersection):
\boxed{(3,3)}

I hope this helped!
