Three more than 1 is equal to 4.
Twice 1/2 is 1.
The number is 1/2.
Check
3 + 2(1/2) = 4
3 + 1 = 4 (yes)
_____
If you insist on writing an equation, rather than solving it the way you could in 2nd grade, here goes ...
3+2x = 4
2x = 1 (subtract 3 from both sides. Does this look familiar?)
x = 1/2 (divide both sides by 2)
