Question

2(y + 1) for = 2

Answer 1

Do you mean:

2(y + 1) = 2 ?

In that case:

2(y + 1) = 2
Divide by two on both side
(y + 1) = 1
y + 1 = 1
Subtract one from both sides
y = 0

Answer 2

or... are you simplifying when y=2
in that case you have
2(y+1)
=2(2+1)
=2(3)
=6
this is the answer if you are asked to simplify... but not solve... your question was not clear (perhaps you made a wee typo in typing it up)
