Answer:
The large number is 17
Step-by-step explanation:
x+y=31⟹x=31−y
2x=y+11⟹x=y+11/2
2(y+11/2)=2(31−y)
y+11=62−2y
3y=51
y=17 x=14
Hope this helps, have a nice day! :)
Larger number is 17 = y
Smaller number is 14 = x
——
X = smaller number
Y = larger number
What we know
X+ y = 31, also written as x = 31-y
2x = 11 + y
Substitute x = 31 -y into second equation
2(31-y) =11+ y
62-2y = 11+ y
51-2y = y
51= 3y
17 = y
X = 31-y
X= 14
