Question

What is the value of k if (1, 1) is a solution of 10x − 3y = k?

Answer 1

Given: 10x - 3y = k, when x = 1 and y = 1.

First, put in x and y and calculate k:

10(1) - 3(1) = k

10 - 3 = k

7 = k

Have a wonderful day! :-)

Answer 2

Explanation:

Substitute the order pair (1.1) for x and y.

10(1) - 3(1) = k

10 - 3 = k

7 = k
