You forget dx in the integral (very important. You need it to the change of variable)
Let y=ln(x+1)
dy=dx/(x+1)
No, you won't be "given a solution", but you can be given some hints. First of all, having "x + 1" in both the numerator and denominator makes things look convoluted. So a substitution would clean things up a bit, giving
Now notice that is the derivative of , so a substitution of the form is appropriate, giving
Surely you can integrate THAT.
