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
Answer is 1704 and to explain just put that you added to get your final answer
1/5(x-y) = 1
x+y = 9
x-y = 5 (x5)
x+y = 9
First you want to create both equations so at least one of the variables (x or y) are the same in both equations, so that is why I multiplied the top one by 5, you multiply the whole equation (both sides)
2x = 14
x = 7
Then you either Plus or minus one from the other, I plused the top one onto the bottom one, then solved for x
7 + y = 9
y = 2
Then put x back into one of the first two equations to get Y
