(1/3)e^(x+1)= 0.5, Is this what you want?
Multiply both sides by 3,
e^(x+1) = 1.5
Take ln,
x+1 = ln1.5
Solve for x,
x = ln1.5 - 1

1/3e^(x+1) = 0.5
3e^(x+1) = 1/0.5 = 2
e^(x+1) = 2/3
taking logs
x + 1 = ln(2/3)
x = ln(2/3) - 1
x = -1.4

· e^(x+1) = 0.5
e^(x+1) = 0.5 · 3 = 1.5
ln [ e^(x+1) ] = ln (1.5)
(x+1) = ln (1.5)
x = ln (1.5) â 1
