Linear Systems Q.
Total of 32 bulbs to be planted. Three times as many crocus bulbs then tulip bulbs. How many of each should be planted?
Does this set up look right? The next step I would do is substitute 3c + t into the 1st equation.

Re: Linear Systems Q.
Hi;
The first equation is fine. The second one is incorrect.
Try this instead:
Now you substitute 3t for c in the first equation. You should have no problems now,
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.

Hi reallylongnickname;
That is correct!
The question could have been solved without resorting to a set of simultaneous equations.
