Answer 1

Step-by-step explanation:

Although anyone can answer it directly but there is also some algebra behind this

let the first number be ‘x’

as the second number is 10 less than the first number so

the second number is ‘x-10’

now according to the given condition the sum of both these numbers is equal to ‘60’ so writing it in mathematical form

‘x’ + ‘x-10’ = ‘60’

i wrote them in single quotes so that you understand they are different numbers

lets call this equation (1)

now simplifying (1)

2x -10 = 60

2x = 60+10

2x=70

x=70/2

x=35

so now we have our first number which is 35

put this value in our second number and we get

35–10=25

there you go we have both our number

35 and 25

to verify if the numbers are correct or not add them and check if the answer is equal to the expected value or not

35+25=60
