Note:-First and last one has already been solved by me in your other two questions .Second one to be solved

#2

  • x+y=15--(1)
  • 2x-y=6--(2)

Add both

  • 3x=21
  • x=7

Put in first one

  • 7+y=15
  • y=8

Explanation:

1)

Let x=larger number

y=smaller number

x+y=59

x-y=13

Now adding these two equations we get

2x=72

x=36

Now as x-y=13

y=x-13=36-13=23

y=23

Therefore the larger number is 36 and the smaller number is 23

(or else u could also write)

The numbers are 36 and 23

---------------------------------------------

2)

Let x=first number

y=Second number

x+y=15

2x-y=6

Now adding these two equations we get

3x=21

x=7

Now as x+y=15,

y=15-x=15-7=8

y=8

Therefore the first number is 7 and the second number is 8

-------------------------------------------

3)

Let x=Larger number

y=smaller number

x-y=3

x-3y=-11

Now on subtracting these two equations we get

2y=14

y=7

Now as x-y=3,

x=y+3=7+3=10

x=10

Therefore the larger number is 10 and the smaller number is 7
