Today we're going to be solving a system of equations using elimination method.
00:04
Since we're given so many decimals, my first step is going to be to multiply these by a multiple of 10 so that i can get rid of any decimals in my equation.
00:13
The top equation, we can see several of our decimals are written to the 100th place, so that means we're going to multiply the entire top equation by 100.
00:22
And if we look at the bottom equation, these are also written to the 100th place.
00:26
So we're going to multiply this one by 100 as well.
00:29
So our new numbers will be negative 15x plus 125y equals 40.
00:41
On our bottom equation, we'll have negative 3x plus 25y equals 8.
00:52
So now we have to get the setup for elimination.
00:55
I need to pick one of my two variables to eliminate.
00:58
I'm going to choose my x and multiply the bottom equation by 5...
