Answer:
x= 1 , y=4
Step-by-step explanation:
x-y= -3 => Equation 1
x+5y= 21 => Equation 2
<u>Substitut</u><u>ion</u><u> </u><u>Method</u><u>:</u>
<u>Substitu</u><u>te</u><u> </u><u>Equation</u><u> </u><u>1</u>=>
x=y-3 <= Equation 3
Put x=y-3 in Equation 2:
x+5y=21
( y-3)+5y=21
y-3+5y=21
6y-3=21
6y=21+3
6y=24
y=24÷6
y=4
Put y=4 in Equation 1:
x-y= -3
x-4=-3
x=4-3
x=1
Hope this helps :)

Answer: 
Answer:
The real distance from shop to store is 24 kilometers.
Step-by-step explanation:
Given:
Distance from the Bake Stars Cafe to the restaurant supply store on map = 3 cm
Also Given:
Scale of the map 1 cm = 8 km
We need to find the real distance from the shop to the store.
Solution:
Now we know that;
Distance from shop to store on map =3 cm
1 cm = 8 km
3 cm = Real distance from shop to store
By using Unitary method we get;
Real distance from shop to store = 
Hence The real distance from shop to store is 24 kilometers.
