If t+8=-12 what's the value of t + 1

To find out what t + 1 is, we first must find out the value of t.
We know that t + 8 = -12, so all we need to do to solve for t is subtract 8 from both sides.

t + 8 = -12

t + 8 - 8 = -12 - 8

t = -20

So now that we know the value of t, all we need to do to find t + 1 is insert the value of t into the variable and solve.

t + 1 = ?

-20 + 1 = ?

-19

And there we have it.
t + 1 = -19
Hope that helped! =)

The reason it gives us t + 8 = -12 is because they want us to figure out what t is. this is very simple trust me:) given our problem.
t + 8 = -12 what we have have to do here is isolate t alone. lets subtract 8 from both sides.
t + 8 = -12 
   - 8 = - 8     the 8 on the left hand side of the equal side is canceled out! and  we have to subtract 8 from -12. lets do the math:)
-12 - 8 = -20 well lets see what we have left of our problem.
t = -20
hey we have our answer we know that t = -20
but the question is asking us to find the value of t + 1 
well lets plug -20 for t
-20 + 1 = -19 since we are adding 1 it moves plus 1 towards the number zero.
so whats the answer? you may be asking..
-19
have a good one :)

merry christmas:D
