Question

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

8x+3y=2
+4x-6y=-7

Answer 1

Answer:

As we cannot find the value of X and y together, we need to assume the value of X so that we can find the value of y or u can do vice versa also and therefore helps us in adding the equation. We must now substitute the values in the equation, and do the usual calculation. Hope it helps u dear!!

Answer 2

Answer:

Multiply first equation by2.

16x+6y=4

Then add this equation with the second

equation

16x+6y=4

4x-6y=-7

Add these two equations

We get 20x=-
