Question

Find 4 solutions of equation 10x+10y=100.

Answer 1

Given equation :- 10x + 10y = 100

divide both side by 10

x + y = 10

x = 10 - y

To find the solution we have to put value of y .

__________

• If y = 0


x = 10 - y

x = 10

___________

• If y = 1

x = 9

________

If y = 2

x = 8

Answer 2

Given equation :- 10x + 10y = 100

( dividing both side by 10 )

10 ( x + y ) = 100

x + y = 10

x = 10 - y

• To find the solution we put the value of y and get the value of x


✴ If y = 5

x = 10 - 5

x = 5

✴ If y = 6

x = 4

✴ If y = 7

x = 3

✴ If y = 8

x = 2

So, the solution are :-

( x , y )

( 5 , 5 ) ( 6 , 4 ) ( 7 , 3 ) ( 8 , 2 )
