Difference means to minus
5 1/4 - 2 3/4 =
[since 1/4 cannot minus 3/4, we need to convert one of the 5 wholes into quarters: 5 1/4 = 4 5/4 ]
5 1/4 - 2 3/4
= 4 5/4 - 2 3/4
= 2 2/4
= 2 1/2

Answer:
The Solution set is (x,y){(2,5)}
Step-by-step explanation:
The given equation is:
6x+4y=32
-6x+4y=8
We will use the elimination method:
By this method we will eliminate the variable x.
6x+4y=32
-6x+4y=8
________
8y=40
Divide both the sides by 8
8y/8=40/8
y=5
Now substitute the value of y in equation 2:
-6x+4y=8
-6x+4(5)=8
-6x+20=8
Move the constant value to the R.H.S
-6x=8-20
-6x= -12
Divide both the terms by -6
-6x/-6 = -12/-6
x= 2
The Solution set is (x,y){(2,5)}....
