The first step to solving this is to solve the equation for x
x = - 21/5 - y
4x + 4y = -14
now,, substitute the given value of x into the equation "4x + 4y = -14"
4( - 21/5 - y) + 4y = -14
next,, solve the equation for y
y∈∅
since this system has no solution for y, your answer is (x,y)∈∅

Answer:
The area of the resulting triangle will be:
Step-by-step explanation:
The area of a triangle is
Let us suppose
As the base and height are scaled a factor of 5.
so
base = 4 × 5 = 20
height = 18 × 5 = 90
as
Therefore, the area of the resulting triangle will be:
1200= 80%
? =100%
to find the ? you can multiply 100(1200)=120000
then 120000 divided by 80= 1500
the original price was 1500, with the discount of 20% you save 300$ and the price is 1200$
