Jake says that the solution to 8.5 - a -5 is that a equals
13.5 because addition and subtraction are inverse
operations and 8.5 + 5 = 13.5. Does Jake's solution make
sense? Explain how you know whether or not Jake's
solution makes sense without solving the equation. Then
draw a model of the problem and solve the equation. Use numbers words and draw a model of the problem and solve the equation
