x - 16.9 = 60.8
To check that the solution is correct, we can solve for x:
x = 60.8 + 16.9
x = 77.7
Our solution is correct because we used all digits 1-9 exactly once and the equation gives the desired solution x = 77.7.
Using the digits 1–9, at most one time each, fill in the blanks to make an equation where the solution is x=77.7. Explain how you know you are correct.
