Answer 6

what do I do

Answer 7

Answer 8

yes

Answer 9

to check your answer, sub in 1 for v
v - 10 = -9
1 - 10 = -9
-9 = -9 (correct)

Answer 10

v-10=-3

Answer 11

what do you have to do to get v by itself ?

Answer 12

subtract 3 from both sides

Answer 13

try adding 10 to both sides and what do you get ?

Answer 14

is it v= 7

Answer 15

watch....
v - 10 = -3 (add 10 to both sides)
v - 10 + 10 = -3 + 10
v = -3 + 10
v = 7

I added 10 to make the 10's cancel out on the left side. But what you do on one side you have to do on the other side. Do you understand ?

Answer 16

you can then check your answer..
v - 10 = -3
7 - 10 = -3
-3 = -3 (correct)
