Answer:

37 and  29

Step-by-step explanation:

x + y = 66

x - y = 8

*******************************************

solve second equation for x

x = y + 8

substitute for x in first equation

y+8 +y = 66

 

2y = 58

y = 29

*******************************************

x - 29 = 8

x = 37

******************************************

x = 37 and y = 29
