Answer:
And that's different from the claim of the student that:
The error of the student is that he/she changes the sign of the inequality from to
and that's not possible since we don't multiply both sides of the equation by -1
Step-by-step explanation:
For this case we have the following inequality:
We want to rewrite the last expression with y in the left and x in the right so we can begin adding 3 in both sides of the inequality and we got:
Now we can divide both sides of the inequality by 2 and we got:
And that's different from the claim of the student that:
The error of the student is that he/she changes the sign of the inequality from to
