Question

Solve the following equation:
y=6x + 1
2x - 9y =30

Answer 1

OK now I see, it was just my browser...

Answer 2

There are 2 methods to solve this. Substitution and elimination. I prefer elimination but we can do the other if you wish. Choose! :-)

Answer 3

actually you can solve it by graphing too, but I wont do that now

Answer 4

OK I do the elimination
there it is important to make the same amount of x-s or y-s.
here we have y=6x+1
if we multiply it by 9 than we will get
9y=54x+9
the second equation is
2x - 9y =30
so we have 9y in the 1st and -9y in the 2nd so if we add them together they will drop out. So we have to add the 2 equations to get.
9y+2x-9y=54x+9+30
2x=54x+39
52x=-39
x=-39/52

Answer 5

Thanks. I think i get it now. i "THINK"

Answer 6

I know you!
