Solve for b.
2 + 10b = 9 + 9b

b=9

Step-by-step explanation:

2+10b=9+9b

get all of your b's on the same side

2+10b=9+9b

   -9b      -9b

2+b=9

subtract 2 from each side

2+b=9

-2      -2

b=9

b = 7

Step-by-step explanation:

So the equation is this:

2 + 10b = 9 + 9b

In order to figure out what the variable b equals we are going to have to put all the variables on one side of the equal sign and all numbers on the other. SO to start we are going to subtract 9b from both sides of the equal sign:

2 + 10b = 9 + 9b

   -  9b         - 9b

Now the equation looks like this:

2 + b = 9

So now we subtract 2 from both sides of the equation:

2 + b = 9

-2        -2

To equal b = 7

Now to see if we are right we are going to substitute 7 in the place of b in the equation:

2 + 10(7) = 9 + 9(7)

2 + 70 = 9 + 63

72 = 72

So our answer to the question  Solve for b.  2 + 10b = 9 + 9b  is that

b = 7
