First equation:

Second equation:

Let us equate the two equations and solve for x.
This implies that;

Group similar terms to obtain:

Simplify:

Divide both sides by 3

Put x=-2 into any of the equations.
I will put x=-2 into the first equation:

This implies that,

Answer:
The system of equation can be used for determine the number of small and the large dogs groomed are
x + y = 22
43x + 75y = 1234
Step-by-step explanation:
Let us assume that the number of small dogs groomed be x.
Let us assume that the number of lagre dogs groomed be y.
As given
Paws at play made a total of $1,234 grooming 22 dogs.
Than the equation becomes
x + y = 22
Paws at play charges $43 to groom each small dog and $75 for each large dog.
Than the equation becomes
43x + 75y = 1234
Therefore the system of equation can be used for determine the number of small and the large dogs groomed are
x + y = 22
43x + 75y = 1234
Answer:
u=2
Step-by-step explanation:
8u-21 = 2u-9
+21 +21
8u= 2u + 12
-2u -2u
6u= 12
divide by 6, u=2 !!
