Answer 8

Add 5 both sides, what's to check?

Answer 9

I saw in the other questions that u want me to add 5, then check that I added 5 correctly by taking it away again....which is pretty stupid, so I will leave the adding and subtracting to u if that's OK.

Answer 11

r+1/3=8/3-1/3 solve and check

Answer 12

This just same thing, take away 1/3 both sides...

Answer 13

so how do u check if d eqn is right

Answer 14

Look, take your example -5+t=11 solve and check

If I was doing this myself, I would just write t=16 (full stop).

Since u requested working, I said "add 5 to each side" .

If u do that correctly, then the original equation is not changed.

If u want to check that u added 5 correctly, do it again as many times as it takes to make you feel certain that u added 5 correctly,

Answer 15

r u mad@ me.ok im sorry 4 asking u question ok

Answer 18

what u need help with? :)

Answer 19

r+1/3=8/3-1/3
r = 7/3 - 1/3
r = 6/3
r = 1/2
to check, plug 1/2 in for r and see if that side of the equation equals the other side (8/3 - 1/3)
