What should be the first step in adding these equations to eliminate y? 12x-2y=-1 + 4x+6y=-4

Multiply the top equation by 3

Step-by-step explanation:

(A) Multiply the top equation by 3

Step-by-step explanation:

The given equations are:

                            (1)

and                     (2)

Now, multiplying equation (1) by 3, we get

Also, adding the above equation with equation (2), we get

⇒

⇒

Thus, on multiplying the top equation by 3, we can eliminate y easily.

Hence, option (a) is correct.
