Answer 1

@KailaMorgan7777 @dumbcow @tom982

Answer 2

b+0.8 = -1
b = -1-0.8
b = -1.8

Answer 3

so it is -1.8 for the asnwer?

Answer 4

tom982 is correct. Notice how he subtracted 0.8 from both sides. This is to undo the +0.8 done to the b on the left which isolates b.

Answer 5

yes hes right!

Answer 6

Thanks @jim_thompson5910, I should have explained that step or included another to show the additive inverse.

Answer 7

That works too. Adding -0.8, the additive inverse of 0.8, to both sides also isolates b.
