So 5k-7=-7
You need to do the opposite of addition,which is subtraction so...
5k-7=-7
+7
__
K=0
and to double check it,replace the (or variable) with our answer (0)...
so
5×0-7=-7
solve the problem...and
-7=-7√
The answer is 4589000.
And the reason, is:
The thousands place is the number 9, so you look at the number next to it on the right side, which is the number 2. Is 2 above 5, or over five? Its below five. So since its below five, the nine will stay as a nine but the rest of the numbers on the right side of the nine will become 0's. But if it was a 5 or above, the nine would become a 10. But you cant say 45810000, so you'd have to change the 8 to a 9.
Hope this helps :)

You spend $180 on pants and shirts. You pay $12 per pair of pants (x) and $15 per shirt (y). You buy 6 more pairs of pants
8 x a = 8 x (-2) = -16
-16 + b = -16 + 3 = -13
-13 is the answer
