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.
