The first equation is
The second equation is
If you sum the two equations you'll cancel y:
And since the sum must be 11, we have y=9.
Answer:2w + 20
Step-by-step explanation:
See, the carpet has a rectangular measure of 10 feet.
It's width is 'w'
We, know that perimeter is the sum of all sides.
Now there are two equal sides which we consider length and two other equal sides for width.
So, we have to add all sides which gives 20 +2w
Also general formula for perimeter is 2(length + breadth)
So, our ans. is 2w + 20
Hope it helps!!!
