Answer:
9 11/12
Step-by-step explanation:
Solve 7 2/3-1 2/4+3 6/8
We are to the above fractions
7 2/3 - 1 2/4 + 3 6/8
The Lowest Common Denominator = 24
(7 - 1 + 3) + ( 2/3 - 2/4 + 6/8)
9 + (16 - 12 + 18/24)
9 + 22/24
9 11/12
Consider the equation

1) First row of the table
Set x=0 and solve as follows:

The answer is y=20 and the pair x-y is (0,20)
2) Second row
Set x=1 and solve, as follows:

The answers are y=10 and (1,10)
3) Third row.
Set y=0 and solve as follows:

The answers are x=2 and (2,0)
