Question

A student is asked to solve the equation below and to justify her/his steps. Identify what, if anything, is incorrect in her/his math or justification. x + 6 = –10

Answer 1

To solve the equation x + 6 = -10, you need to isolate the variable x. The student made a mistake by adding instead of subtracting 6 from both sides of the equation. The correct solution is x = -16.

Step-by-step explanation:

The student is asked to solve the equation x + 6 = -10. To do this, we need to isolate the variable x. The student seems to have made a mistake when simplifying the equation. Instead of subtracting 6 from both sides of the equation, the student added 6 to both sides, which is incorrect. The correct steps to solve the equation are:

1. Start with the equation x + 6 = -10.
2. Subtract 6 from both sides of the equation to isolate the variable: x = -10 - 6.
3. Perform the subtraction: x = -16.

Therefore, the correct solution to the equation x + 6 = -10 is x = -16.

Answer 2

The - number has to t o be more then 6 in order to get -10. Answer= -16
