Question

+ 3
= 10X + 3 Y equal to 10 ​

Answer 1

Answer:

10X+3Y =10------------------(1)

3y=10+10x-------------------(2)

substitute 3y=10+10y

10X+10+10x=10

multiple by -

-(20x+10)=10

-20x-10=10

-20x=20

x=20/-20

x= -1

putting in (1)

10x+3y= 10

-10+3y= 10

3y= 10+10

3y= 20

y= 20/3

y= 6.6.........................

here x=-1

y=6.6 (appropriate)
