What is the answer to 5x+2=12

5x + 2 = 12

5x = 10

x = 2

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.
