{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!!!!

Answer:
A.
Myra can make 18 or fewer copies
Let n be the no. of copies
The cost:
5 + 3n《59
3n《54
n《18
5 1/3 yds
2/3 yds of fabric per pillow
8 pillows
2/3* 8 = 16/3 yds of fabric
Changing from an improper fraction to a mixed number
3 goes into 16 5 times with 1 left over
