99x + 101y = 499 ; 101x + 99y = 501
  • 1 answers

Yogita Ingle 4 days, 21 hours ago

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; x + 5y = 4

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 ; m - 6n = -7
  • 1 answers

Yogita Ingle 1 week, 2 days ago

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

Yogita Ingle 1 week, 4 days ago

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 108 m
  Order of magnitude = exponential part = 108 m

3x + 2y = 29 ; 5x - y = 18
  • 1 answers

Yogita Ingle 1 week, 5 days ago

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
