Today, we are solving systems of inequalities with two variables, in this case specifically applying strategies to a word problem.
00:11
So in this case, in this word problem, the first thing we need to do is set up two equations.
00:17
So we have our system.
00:19
Now, we need to find the solution amount of each specific saline solution.
00:27
So those will be our x and our one.
00:30
Now, we know x plus y is going to equal a total of 200 milliliters of solution.
00:38
We also know that 0 .30 for 30 % of x plus 0 .10 % of y is going to equal 0 .12 % of 200.
00:57
So those are our two equations that form our system.
01:01
We want to solve this.
01:02
We can use any strategy.
01:05
I'm going to use substitution...
