UNPROJECT13

Here is an algebraic euation: 2x+5=13
The first step your going to do is to isolate the variable by canceling
the constant +5 which would look like this
2x+5-5=13-5

Because we've added -5 to the left we need to add -5 to the right to balance
2x+5-5=13-5

Once you have balanced both sides
you will divide both sides by 2 which
look like this

2x = 9
2      2

Then you cancel the twos you left  of with x then you divide
8 and 2 then you get x=4

now you verify by using the original equation

2x+5=13

Then you substitute the value of x which is 4
SO
now
2(4)+5=13
8+5=13
Now, I know that my answer is right because they are balance
