2x+3y= -17
5x+2y= -4
You must cancel either the x or y out to solve so i'm going to cancel the x.
-5(2x+3y= -17)
2(5x+2y= -4)
This simplifies to:
-15x -15y=85
15x+4y= -8
The -15x and 15x cancel out leaving you:
-15y=85
4y= -8
You add them top numbers by the bottom and get:
-11y=77
Then divide by -11 to get y by its self.
y= -7
Now that you know what y is just plug it in to either original problem. I will use the second one.
5x + 2(-7) = -4
5x -14 = -4
5x = 10
x = 2
So the answer is (2,-7) or x=2 and y=-7

Answer:
Dimensions of rectangle are 
Step-by-step explanation:
Area of rectangular knitted blanket = 
We need to find the dimensions of blanket.
If we need to find the dimensions, we need to find the factors of area.
Factoring:
We will break the middle them -11x
- Adding 4x-15x we get -11x
- Multiplying 4x and -15x we get -60x^2 (Product of -6 and 10x^2)
Now, finding factors
So, factors of 
are 
So, dimensions of rectangle are
