5 x [B] + 15 = 25
Subtract 15 from both sides leaving you with:
5 x [B] = 10
The only thing that you can multiply 5 by to get 10 is 2. Therefore [B] = 2 and the answer is:
5 x 2 = 10

This is a two step equation... you need to do the OPPOSITE of the Order of Operations to solve the problem - to isolate the variable....
5t + 15 = 25
Do the opposite of adding 15 to both sides ( subtract 15 to both sides)
5t + 15 - 15 = 25 - 15
5t + 0 = 10
Do the opposite of multiplying 5 to both sides (divide both sides of the equation by 5 )
5t / 5 = 10 / 5
t = 2
* REMEMBER THE GOAL OF THE PROBLEM IS TO ISOLATE THE VARIABLE!!!
