00:01
So let us assign our variables first.
00:04
Let x as our first number and our y is the second number.
00:13
So some of the squares, it is stated to some of these numbers are the squares, these numbers added to each other, equivalent to 1 ,45.
00:21
That means x squared plus y squared is equivalent to 1 ,4 ,5.
00:25
And then one of the numbers, the squared of one of the number is 3.
00:33
Let's show me it's x squared of x is equivalent to 9.
00:39
Okay, so no, it's not 9.
00:42
It's 3, i'm sorry.
00:43
It's 3 based on the given.
00:45
Okay, so these are our given.
00:47
Now we can solve for our x by we square this two.
00:54
Okay, take the square of this two.
00:56
We square this, we will be getting rid of the square root sign.
01:01
So we now have x equivalent to 3 squared.
01:04
Which is 9.
01:06
So this is therefore the value of our first number, x.
01:10
So now we have the value of our x.
01:11
We can substitute it to our first equation, which is x squared plus y squared equivalent to 1 .45...
