okay so if - 19 is equal to 17 + k divided by 5, first you figure out what you have to do to 17 to get -19. in this case, all you do is subtract 17 from 17 to get 0, then subtract 19 from 0 to get -19. then you add 17 and 19 to see how much you subtracted from 17 to get -19, so you subtracted 36 from 17. now you add the - sign to the 36 so that means instead of subtracting a positive number you're adding a negative number (it has the same effect) so you now need to know what, when divided by 5, equals -36. so just multiply -36 by five to get -180. so k = 170
Step-by-step explanation:
-19 = 17 + -180/5
-180/5 is -36
-19 = 17 + -36
17 + -36 = -19
-19 = -19
(sorry this is a lot of info but its harder to explain if i cant say a lot)
