Let us use a trick to solve it quickly

99x + 101y = 499 ............ i

101x + 99y = 501............ ii

subtract i from ii

2x - 2y = 2

x - y =1

x = 1 + y ........ iii

add i and ii

200x + 200y = 1000

x + y = 5 .................................. iv

Now from iii and iv , we get 1 + y + y = 5 or 2y = 4 or y = 2 ...... v

again from iii and v , we get x = 1 + 2 = 3

Hence x = 3 , y = 2

5x + 2y = -3 ........ (i)

x + 5y = 4

x = 4 - 5y ........... (ii)

Put (ii) in (i), we get

5(4 - 5y) + 2y = -3

20 - 15y + 2y =-3

- 13y = - 3 - 20

-13y = -23

y = 23/13

Put value of y in (ii), we get

x = 4 - 5(23/13)

x = (52 - 5)/13 = 47/3

5m - 3n = 19 ......... (i)

m - 6n = -7 ........... (ii)

Multiple (i) by 2 , we get

10m - 6n = 38........... (iii)

Subtract (iii) and (ii), we get

(10m - 6n)- (m - 6n) = 38 - (-7)

10m - 6n - m + 6n = 38 + 7

9m = 45

m = 5

Put m = 5 in (ii) we get

5 - 6n = -7

-6n = -7 - 5

-6n = -12

n = 2

Any number can be written as the product of a number between 1 and 10 and a number which is power of ten. The exponential part of a particular measurement is called order of magnitude of a quantity.

Example: Diameter of Jupiter = 142700000 m = 1.427 x 10^{8 }m

Order of magnitude = exponential part = 10^{8} m

3x + 2y = 29 .......... (i)

5x - y = 18 .......... (ii)

multiply equation (ii) by 2 and add in (i) , we get

3x + 2y = 29

+10x - 2y = 36

____________

13x=65

x = 65/13= 5

now put in (ii), we get

5(5) - y = 18

25 - y = 18

25 - 18 = y

7 = y

and x = 5
