It's the 1st one. I hope this helps!
To find the length, divide the area by the width:
Length = 20.5 / 2.5 = 8.2 cm
{x=-1/3-10/3y
5x+20y=5
5(-1/3-10/3y)+20y=5
solve the equation
.
.
Y=5
substitute the value of y into the equation
x=-1/3-10/3×2
.solve the equation
.
.x=-7
(x,y)=(-7,2)
{3×(-7)+10×2=-1
5x(-7)+28×2=5
simplify
{-1=-1
5=5
the ordered pair is asolution
(X,Y)=(-7,2)
That's all!!!!
