Answer:
So the first step is asking you to write the explanation on your own paper (Easy! :)
The whole equation is designed for you to get the variable "x" by itself so that you know what number it is equal to. In order to do this you need to follow the steps.
So for the second step you need to add 1 to both sides. This step is so that you can get rid of the 1 on the left side, to do this you need to add 1 because this will cancel out on the left side since you are substracting it. BUT if you add one on the left side, you also need to add it to the right side!!! (Whatever you do on one side of the equal sign you need to do on the other side)! So add one on both sides this will get rid of the 1 on the left and turn the 6 to a 7 on the right side.
NEXT STEP (Multiply both sides by -2) So (-1/2) is the same as saying 1 divided by -2 which is -0.5 as a decimal. If you want to cancel out a fraction you want to multiply it by the denominator (aka bottom number), in this case that number is -2. So if you multiply (-1/2) by -2 this cancels that fraction out on the left side and it disappears, BUT you must do it on the right side too! So you multiply 7 by -2 which is equal to -14.
Now you're left with 5x = -6! Your final step is to get rid on the 5 on the left side. To do this you simply divide it by 5 so that it cancels out on the left side and you're left with x. BUT you still divide on the right side, so x is equal to (-6/5).
I hope this helps!
It is all about getting x by itself.
