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!!! :)

Pls mark me as brainliest. Only one remaining. Pls pls~

Answer:

2.8 and 1.5

Step-by-step explanation:

Let the two numbers be x and y .

x + y = 4.3   \:  \:  \:  \:  \:  (1)\\ x - y = 1.3 \:  \:  \:  \:  \: (2) \\  \\ adding \: (1) \: and \: (2) \\ x + y = 4.3 \\plus \\  x - y = 1.3   \\ equals\:  \\ 2x = 5.6 \\ x =  \frac{5.6}{2}  = 2.8 \\ substitute \: x = 2.8 \: in \: (1) \\2.8 + y = 4.3 \\ y = 4.3 - 2.8 \\ y = 1.5

THEREFORE THE TWO NUMBERS ARE 2.8 AND 1.5 !

I HOPE IT IS HELPFUL !

SWEET DREAMS !
