Question 538697
This is an example of a linear equation  : 2x + 4 = 10

2x + 4 = 10

The goal is to find what X is equal to, your final answer is X = (answer)
The first step in solving this equation is to subtract 4 from both sides. (Remember that what you do to one side you must do to both sides).

2x + 4 - 4 = 10 - 4

2x = 6

Now you just need to divide both sides by 2, and you will get the final answer:

x = 3

Let's do another one.

{{{ x/3 - 12 = 36 }}}

{{{ x/3 - 12 + 12 = 36 + 12 }}}

{{{ x/3 = 48 }}}

{{{ x = 16 }}}

Do you see that? You need to do the opposite operation (subtracting and adding are opposite, division and multiplication are opposite) to both sides. So when you see x - 1 = 12, you know to add 1 to 12 to get 13, and to cancel out the x + 1 to get simply x. x = 13.
