Question

What should be the first step in adding these questions to eliminate y

Answer 1

The answer is B multiply the bottom equation by 2

Explanation:

3x + 4y = 8

6x - 2y = 9

By multiplying the bottom equation by 2 it will be

12x - 4y = 18 ⇒ add this with the first equation

4y + -4y = 0 so y is eliminated
