Hey there! :D
We can just add the numbers together to create an equation we can solve.
2x+y-10=0
x-y-5=0
3x-15=0 <== expression added together
3x=15
Divide both sides by 3.
x=5
Now, plug that in to solve for y.
x-y-5=0
5-y-5=0
Add 5 to both sides.
5-y=5
Subtract 5.
y=0
y=0
I hope this helps!

We are tasked to determine the difference between the two expressions such as 9+3x and 4+2x². In order for us to solve this, we need to arrange the terms in descending order such as shown below:
(3x + 9) and 2x² + 4
Then, we need to perform subtraction in the same terms only such as 9 and 4:
3x +9 - (2x² + 4)
3x + 9 -2x² - 4
3x + 5 - 2x²
Then arrange in descending order such as:
2x² + 3x + 5
The answer is 2x²+3x+5.
Perimeter of older
Perimeter of newer
As w is constant cancel it
Ratio
Ratio of area is also same
So
- 5/3=12500/x
- 5x=37500
- x=37500/5
- x=7500m²
