do you know to solve?
OpenStudy (anonymous):
I did and got x= 1666667 and y= 333333

But I checked it but it was an approximate value
OpenStudy (anonymous):
To solve this first multiply second equation by 6 or 15 ok we multiply 2nd equation by 6 . Then subtract second equation from first, Then then u will get value of y , after that just put that value( of y) in any above equation u will get value of x...
OpenStudy (welshfella):
6x+15y=15000000 -6x - 6y= -12000000 adding 9y = 3,000,000 y = 333333.33
