The 'answer' is the number that 'x' must be in order to make the equation a trye statement.

For example, if you try ' 1 ' for the answer, then you have to put ' 1 ' in place of 'x' and see if the statement is true:

5x + 2 = 12
5(1) + 2 = 12
5 + 2 = 12
7 = 12 <== This is not true. So ' 1 ' is not the answer.

Here are the steps:

5x + 2 = 12

Subtract 2 from each side:

5x = 10

Divide each side by 5 :

x = 2

There's the answer.
