Answer:
36
Step-by-step explanation:
Here we a given a rule
It say
÷
And we are given the values of x and y as
x=4 and y = 9
Let us replace them in the rule we are provided with
÷
Applying DMAS rule, which says, first Division ollowed by Multiplication addition and then subtraction .
We first divide 9 by 3
9÷3 = 3
Hence
÷
Now we square first



Hence our final answer will be 36
<u>Given</u>:
The given equations are
and 
We need to determine the pair of numbers that is a member to the system of equations.
<u>Pair of numbers:</u>
The pair of numbers can be determined by solving the system of equations.
Let us use the substitution method to solve the equations.
Substituting
in the equation
, we have;




Thus, the value of x is 1.
Substituting x = 1 in the equation
, we get;



Thus, the value of y is 7.
Hence, the pair of numbers that is a member of both the equations are (1,7)
