anonymous 4 years ago The average of two numbers, a and b, is given by: A=a+b/2 If the average of two numbers is 73, and if one of the numbers is 59, then what is the other number? Please show all of your work.

I tried plugging it but I am having hard time

$A=\frac{a+b}{2}$ $73=\frac{59+b}{2}$ Multiply both sides by 2 $146=59+b$ subtract 59 from both sides $87=b$
