How do you solve using elimination of #2x - 3y = 12# and #3x + 5y = -1#?
On paper you should line the equations up, one below the other:
In elimination, you have to find the least common multiple between one of the variables. I prefer to eliminate
You’ll have to multiply
Now you have to combine the equations by subtracting the bottom equation from the top:
Notice that we added
Now to isolate
Now that we found
Now, we subtract
Divide both sides by
And there you go!
Hope this helps!
