Answer:

b

Step-by-step explanation:

2x + 2 = 1x + 5

combine the like terms.

2x + 2 = 1x + 5

-2x        -2x  

------------------

2 = -1x + 5

isolate the -1x.

2 = -1x + 5

-5          -5

----------------

-3 = -1x

solve for x.

-3/-1 = -1x/-1

3 = x

so b. correct me if any of this is wrong.
