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.

  The solution is x = 19.
• Multiply both sides by 7 The solution is x = 84.

What equation matches this situation?
Robyn had some video games then bought 4 more.  Now she has a total of 10 games.

• v - 4 = 10
• v + 4 = 10
• 10 - 4 = v
• Answer not Given

Translate 4 more than x equals 7 into an equation and solve. 

• x+4=7
  x = 11
• x+4=7
  x = 3
• x-4=7
  x = 11
• x-4=7
  x=3

Translate:
