Diana,
First@Solve[x + 1 == 2, x]

Hi,
I am trying to write a program which defines a variable with the
results of a Solve equation.
So, if I write
Solve[x+1=2,x]
I get {{x -> 1}}
I have not been able to figure out how to define a variable to the
result, so that if I then type
x1 = %, for example, it defines x1 as 1.
I know this must be simple, but I didn't find it in the Help material.
Thanks in advance,
Diana
