Question

A student’s work is shown below.

y – 12.7 = 32.75

y – 12.7 – 12.7 = 32.75 – 12.7

y = 20.05

Which is the best statement about the student’s work?

The student solved the problem incorrectly. The student should divide both sides of the equation by -12.7 to create a zero pair.
The student solved the problem incorrectly. The student subtracted incorrectly because 32.75 – 12.7 is 20.68.
The student solved the problem incorrectly. The student should add 12.7 to both sides of the equation to isolate the variable, y.
The student solved the problem correctly. Subtracting 12.7 from both sides of the equation isolates the variable, y.

Answer 1

Answer: The student solved the problem correctly. Subtracting 12.7 from both sides of the equation isolates the variable, y.
