What is 12 minus 7b plus 10b equals 18?

Answer 1

First lets set up the equation.

12 - 7b + 10b = 18.

Now lets combine all like terms on the left hand side.

12 - 7b + 10b = 18

12 + 3b = 18

Now lets combine all like terms using the like terms on the left side and on the right side.

12 + 3b = 18

-12 -12

3b = 6

Now lets divided (since the 3 is being multiplied to the b).

3b/3 = 6/3

So your final answer is:

b = 2
