√3x + √2y=0
dent?
coin
9. Solve the following equations:
x + y = 10
x - y = 12
r-axis?
​

Answer 1

Step-by-step explanation:

8) Given lines are 2x+3y=0

=>2x=-3y

=>x= -3y/2......(1)

and √3x+√2y=0....(2)

Substituting the value of x in (2) then

=>√3(-3y/2)+√2y=0

=>-3√3y/2+√2y=0

(-3√3y+2√2y)/2=0

=>y(2√2-3√3)=0

=>y=0

now from (1) x=-3(0)/2=0

The solution is (0,0)

9)

Given lines are x+y=10...(1)

and x-y=12....(2)

from (1)&(2)

x+y=10

x-y=12

---------

2x=22

--------

=>x=22/2=11

from (1) ,11+y=10=>y=10-11=-1

The values of x=11,y=-1
