One Step Equations Problem Solving

How can you "convince" someone that your solution to an equation is correct?

• Tell them ... "Just trust me!"

• Substitute your solution for the variable and make sure that both sides of the equation are "balanced."

• Just keep showing them how to solve the equation.

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.
