What is the difference of the values of the two variables in this system of equations? y = 2x + 1 x + 3y = 10 a. 0 b. 1 c. 2 d. 3

 The correct option is (C) 2.

Step-by-step explanation:  We are given to find the difference of the values of the two variables in the following system of linear equations :

Substituting the value of y from equation (i) in equation (ii), we get

From equation (i), we get

So, the values of the variables are x = 1  and  y = 3.

Therefore, the difference in the values of the variables is given by

Thus, the required difference in the values of teh variables is 2.

Option (C) is CORRECT.
