Question

find two decimal number whose sum is 1 and the diffrence is 0.20​

Answer 1

Answer:

0.60 0.40

Step-by-step explanation:

0.60 + 0.40 = 1.00

0.60-0.40= 0.20

Answer 2

Step-by-step explanation:

x+y=1----(I)

x-y=0.2----(II)

In equation I,

x=1-y

Substituting the value of x in equation II

=> 1-y-y=0.2

=>1-2y=0.2

=>-2y=0.2+1

=>-2y=1.2

=>y=-1.2/2

=-0.6

Substituting it in equation 1

x-0.6=1

=>x=1+0.6

=>x=1.6

I think this is the answer
