Which statement is true about their work? Neither student solved for k correctly because K = 2 and StartFraction 1 over 8 EndFraction. Only Adler solved for k correctly because the inverse of addition is subtraction. Only Erika solved for k correctly because the opposite of One-half is Negative one-half. Both Adler and Erika solved for k correctly because either the addition property of equality or the subtraction property of equality can be used to solve for k.

What is true about Adler and Erika's workings

Analyzing Adler's work;

Adler subtracted 1/2 from both sides

Solving the expression on the left-hand side

Solving the expression on the right-hand side

Hence:

So, Adler's workings is correct

Analyzing Erika's work;

Erika added -1/2 to both sides

Solving the expression on the left-hand side

Solving the expression on the right-hand side

Hence:

So, Erika's workings is correct

Both workings are correct
