Question

sum of two number is 60 and their difference is 30 a) If smaller is x, the other number is _____.​

Answer 1

Answer:

let the two numbers be x and y

Then x+y=60-------------equation 1

         x-y=30------------equation 2

By elimination method of addition,

2x=90

x=90/2

x=45

Now, put x=45 in equation 1

45+y=60

y=60-45

y=15

Therefore, x=45 and y=15.

sum of two number is 60 and their difference is 30 a) If smaller is x, the other number is 15.

Hence, your answer is 15
