    can you simplify the left hand side first?

    2(x + 1), you need to distribute here, are you familiar with distributing?

    so now you have 2x + 2 = 2x + 5

    now subtract 2x from both sides

    what do you end up with?

    ummm... I think it is 2x = 2x + 3

    well that is correct, if you subtract 2 from both sides, but i was saying to subtract 2x from both sides

    so if you have 2x + 2 = 2x + 5, and you subtract 2x from both sides you get 2 = 5, since 2 does not equal 5 this does not have any solutions

    hint: if we apply the distributive property of multiplication over addition at left side, we can write this: 2x+2=2x+5
