Step-by-step explanation:
Let the two numbers be x and y respectively.
now,
x+y=4.3 — eq. 1
x-y=1.3 — eq. 2
In eq. 1
x+y=4.3
x= 4.3-y
substitute this value of x in eq.2
So x-y=1.3
(4.3-y)-y = 1.3
4.3-2y = 1.3
4.3-1.3 = 2y
3= 2y
y= 1.5
Substitute the value of y in eq. 1
x+y=4.3
x+1.5 =4.3
x= 4.3-1.5
x=2.8
Hope it helps!!! :)
