$i+6i=7i$

In this case, $i$ can be treated like a variable with a real value, so the rule $ax+bx=(a+b)x$ applies. This gives us:

$i+6y=1i+6i=7i$

$7i$

Even though it is not a variable, we can treat $i$ like one, and combine these. In algebra, if we had

$x+6x$ , we would say this is $7x$ , because we saw we had like terms. Instead of this, we have

$i+6i$

We can combine these to get $7i$ because we see they both have an $i$ . If you have like terms, we can always condense them into one term.

Hope this helps!
