Answer 3

can you simplify the left hand side first?

Answer 4

No, I don't believe so

Answer 5

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

Answer 6

actually yes.

Answer 7

ok so please distribute to simplify that

Answer 8

2x + 2 right ?

Answer 9

correct

Answer 10

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

Answer 11

yes

Answer 12

now subtract 2x from both sides

Answer 13

what do you end up with?

Answer 14

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

Answer 15

I think I did it wrong

Answer 16

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

Answer 17

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

Answer 18

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