Carol’s class had 25 students on roll. After some new students join her class, the number of students increases to 36. Write an equation to determine the number of students who joined Carol's class.

• 25 + x = 36

• x – 36 = 25

• 36x = 25

• 36 + x = –25

In the equation
x + 7 = 12
7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation? 

• Subtract 7 from both sides. The solution is x = 5.

• Add 7 to both sides.
  The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.
