While David was solving the equation 100x + 300 = 500, he wondered if he could first change the equation to x + 3 = 5. What do you think? Homework Help ✎
Solve both equations and verify that they have the same solution.
Solve both equations for x.
x + 3 = 5 100x + 300 = 500
x = 2 100x = 200
x = 2
They have the same solution.
What could you do to the equation 100x + 300 = 500 to change it into x + 3 = 5?
Is there a common factor in the first equation?
