Question

Toni needs to solve the equation q - 6 = -2 and then create the number line that represents the solution.

Which is NOT a step in that process?

A. Check the solution by substituting q = 4 back into the original equation.
B. Add 6 to both sides of the equation.
C. Plot the solution, q = 4 on a number line.
D. Subtract 6 from both sides of the equation.

Answer 1

D; it is NOT a step in the process.

Explanation:

You would not subtract 6 from either side of the equation, you would only add.

q-6=-2

+6 +6

q=4.

A is correct because you would want to check if your solution is correct by substituting q for 4:

4-6=-2 (which is true)

B is correct, because as previously stated, you must add 6 to both sides to get the correct answer.

C is correct because the question specifies graphing the solution.

Answer 2

Answer: D. Subtract 6 from both sides of the equation.

Because u need to do the inverse
