Question

Explain each o the three steps that are required to get x by itself 2x-9=19

Answer 1

x = 14

Explanation:

So, you start with the problem, obviously.

2x - 9 = 9

From there you need to get the non x term out of the statement by adding the opposite (to both sides).

2x + (-9) = 19

+ +9 = 9

2x = 28

Finally, you divide, or cancel out the number in the term with the variable.

(2x / 2) = (28/2)

x = 14

Hope this helps!
