Answer:
The ordered pairs that are solution to this equation are:
(8,1) and (10,3)
Step-by-step explanation:
Given statement is:
"difference of two variables x and y is 7"
This can be mathematically written as:
[tex]x-y = 7[/tex]
To solve this we have to put y = 1 and y = 3
Now,
Putting y = 1 in the equation
[tex]x-1 = 7\\x = 8[/tex]
Putting y = 3 in the equation
[tex]x-3 = 7\\x = 7+3\\x = 10[/tex]
Ordered pairs are of the form (x,y)
Hence,
The ordered pairs that are solution to this equation are:
(8,1) and (10,3)
