Question

the sum of two numbers is 39 if the greater number is 5 more than the smaller one find the numbers by substitution method

please solve this by substitution method
​

Answer 1

Answer:

22,17

Step-by-step explanation:

1) let take numbers be x and y

2)here let take x>y

3) now according to question we have

x=y+5

4) it is given that sum of number is 39

therefore,

x+y=39

5) substituting the value of x from step3 to step4

y+5+y=39

2y+5=39

2y=34

y=17

6) now putting the concluded value of y from step5 to step3

x=17+5

x=22

conclusion:-

hence we get both the values x and y

i.e.:- x=22 and y=17

verification

putting both the values in step3

we get

22=17+5

verified

Answer 2

answer:

let the smaller no. be x

and greater no. be x+5

According to question

= x+x+5 = 39

= 2x+5 = 39

= 2x = 39-5

= 2x = 34

= x = 17

so,

smaller no. = 17

greater no. = 17+5

= 22
