hope it helps u mark me as brainlist and like my answer pls
Step-by-step explanation:
let numbers x and y
x+y=36. 1
x-y=6. 2
adding 1 and 2
(x+y)+(x-y)=36+6
x+y+x-y=42
2x=42 x=42/2
x=21
x+y=36
21+y=36
y=36-21
y=15

Answer:
let small no.= x &
large no. = y
from condition first
2x-2y =6 eqn 1st
&
from condition 2nd
x+y=36. eqn 2nd
let multiply eqn 2nd by 2 - (for making equla eqn)
2/x+2/y=2/36
2x+2y=72 - eqn 3rd
add eqn 1st & 3rd
2x-2y=6
+ 2x+2y =76
4x=82 - ( ans of adding eqn)
x=0.04878
put value of x in eqn 2nd
x+y=36
0.04878+y=36
y= 36 - 0.04878
y = -35.95122
