Three times a first number decreased by a second number

ki77a [65]

Answer:

The two numbers are 3 and 5

Step-by-step explanation:

$3X-Y=12\\X + 4Y=17\\$

Multiply top equation by 4 to cancel out the Ys

$12X - 4Y = 48\\X + 4Y = 17\\\\13X = 65\\X = 5\\$

Since X =5, we can plug it into either of the top two equations to find out the value of Y

$3(5) - Y = 12\\15 - Y = 12\\Y = 3$

To double check

$3(5) - 3 \\15 - 3\\12\\\\5 + 4(3) \\5 + 12\\17$

$GM(a,b)=\sqrt{ab}$

So, if the product is 8, the geometric mean is $\sqrt{8}=2\sqrt{2}$
