Question

What is the first step in solving this system of equations using elimination?



2x – 4y = 6

Answer 1

there is only one equation here.

Answer 2

The first step is to make opposites of one variable.

IE: 2x + 5y = 10
x + 10 y = 50
Multiply the second equation by -2 to make them line up.
2x + 5y = 10
-2x - 20 y = -100
Then add the two together:
-15 y = 90
But this doesn't relate to your problem since you only have one equation, you need two.
