Question

the difference of two variables x and y is 7. find two ordered pairs that satisty this equation if the values of y are 1 and 3... Show your solution​

Answer 1

The ordered pairs that are solution to this equation are:

(8,1) and (10,3)

Explanation:

Given statement is:

"difference of two variables x and y is 7"

This can be mathematically written as:

`x-y = 7`

To solve this we have to put y = 1 and y = 3

Now,

Putting y = 1 in the equation

`x-1 = 7\\x = 8`

Putting y = 3 in the equation

`x-3 = 7\\x = 7+3\\x = 10`

Ordered pairs are of the form (x,y)

Hence,

The ordered pairs that are solution to this equation are:

(8,1) and (10,3)
