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)∈∅

We know that :
From the figure, We can notice that :
↔ Opposite side of Angle Q is 9 units
↔ Hypotenuse is 15 units
We can set up a proportion.
600/24 = x/40
Cross multiply:
600 * 40 = 24 * x
24000 = 24x
Divide 24 to both sides:
x = 1000
So you need 1000 grams of flour to make 40 scones.
Answer:
an-1-9
25n-1-9
25n-10=0
25n=0+10
25n=10
divide both sides by 25
25n/25 =10/25
n=2/5
