Answer:
x=13
y=8
Step-by-step explanation:
let the greater number be x and the smaller number be y.
<u>Now</u><u>,</u>
from first condition,
x = y + 5 --------1
from second condition,
x + y = 21
or, x = 21 - y --------2
from equation 1 and 2,
y + 5 = 21 - y
or, 2y = 16
y = 8
now,
putting the value of y in equation 1
x = 8 + 5
= 13
Answer:
13.
Step-by-step explanation:
x+x+5=21
2x+5=21
