Question

Solving equations involving addition and subtraction.
I am SO confused, I took a test and got nothing right... Help Please!

Answer 1

5+x=6 ? like this?
or like this 5-x=6?

Answer 2

something like x-16= -36. Sorry I'm kinda stupid :P

Answer 3

you want to isolate the x
you have minus 16 on the side with the x
to undo the minus you add

Answer 4

so since you have minus 16
you do plug 16 on both sides

Answer 5

no 1 is stupid you just had a slow moment

Answer 6

Oh... That makes way more sense then everyone else says.. Thanks :)

Answer 7

x-16=-36
add 16 to both sides
x-16+16=-36+16
we did this because we knew -16+16=0
so you would end up with
x+0=-36+16
which will allow us to just write x instead of x+0 on that left hand side
x=-36+16

Answer 8

np

Answer 9

Oh... That makes way more sense then everyone else says.. Thanks :)

Answer 10

Answer 11

Thanks Xavier!

Answer 12

your welcome and my name is kasaan

Answer 13

no.... you add the 16 if it says minus
you do the opposite to each side to isolate x.
so the answer t your example is -20
