EX: If you were investing $7000, what would you invest at 5% and 6% to reach close to a 700 interest?

@&

You couldn't get $700 interest at those rates. 6% of $700 is only $400.

Let's say you wanted to get $400, which is feasible, since 5% interest would get you $350 and 6% would get you $420.

You could invest amount x at 5% and $7000 - x at 6%. Your interest would then be

.05 * x + .06 * (7000 - x).

Set this equal to $400 and solve, and you'll get the result.
