Question

Add the equations. Two-Variable Systems: Elimination (question is linked with the screenshot below)

Answer 1

2y = 24

Explanation:

5x – y = -1

+ - 5x + 3y = 25

2y = 24

Hence, A. 2y = 24 is the right answer.

Answer 2

2y = 24

Given -

5x - y = (-1)

-5x + 3y = 25

To find - Summation of this

5x - y = (-1)

+ (-5x) + 3y = 25

adding both the equation we get,

5x +(-5x) - y + 3y = (-1) + 25

0 + 2y = 24

2y = 24.
