Answer:
x is 13
y is 2
Step-by-step explanation:
let the two numbers be x and y
so...given that -
x + y = 15 ... equation 1
x - y = 11 .... equation 2
now we add both the equations, we get
× + y = 15
+ x - y = 11
-------------------
2x = 26
thus, x = 13
substituting x in equation 1, we get
13 + y = 15
y = 2
Answer:
x= 16 , y= 5
