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

x = 14

Step-by-step 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!

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

expression #3 is not equivalent. the others are.
