## anonymous 3 years ago The average of 2 numbers is 17. One of those numbers were 22, what was the other number?

To find average of two numbers, call numbers a and b$\frac{ a+b }{ 2 }=average$

2. anonymous

yes i know that. That does not answer my question though

$\frac{ x+22 }{ 2 } = 17$ Multiply both sides by 2 x+22 = 34 -22 -22 x=12
