Question

Emily chooses two numbers. She adds the two numbers together and divides the result by 2.

Answer 1

(x+y)/2= 44

let x- 12

(12+y)/2= 44

12+y = 44*2

12+y= 88

y= 88-12

y= 76

Answer 2

Easiest way is algebra so
x+y are 2 numbers
if (x+y)/2=44
and x or y=12 (pic one)
so if x=12
subsitute
(12+y)/2=44
multiply both sdies by 2 to clear fraction
12+y=88
subtract 12 from both sides
y=76

the numbers are 12 and 76
