Question

Find two numbers if their sum is 6.1 and their difference is 1.6

Answer 1

let first no be X

2nd no be y

ATQ,

Case 1.

x+y = 6.1 --- 1 eq.

Case 2.

x-y = 1.6 ---- 2 eq.

from eq. 1 and 2.

x+y=6.1
x-y=1.6

2x = 7.7

x = 7.7/2
$7=7 \div 2 = 3.85$

x= 3.85

y = 9.1-3.85
$6.1 - 3.85 = 2.25$

y= 2.25
