<br><pre>
(A) Without simplifying along the way....<br>
Step1: Think of a number  ----------------  x
Step2: Add 7  ----------------------------  x+7
Step3: Double your answer  --------------- 2(x+7)
Step4: Subtract 4  ----------------------- 2(x+7)-4
Step5: Divide by 2  ---------------------- (2(x+7)-4)/2
Step6: Subtract the number you started  -- ((2(x+7)-4)/2)-x
Step7: write down your answer<br>
(B) Simplifying as we go....<br>
Step1: Think of a number  ----------------  x
Step2: Add 7  ----------------------------  x+7
Step3: Double your answer  ---------------  2(x+7) = 2x+14
Step4: Subtract 4  -----------------------  (2x+14)-4 = 2x+10
Step5: Divide by 2  ----------------------  (2x+10)/2 = x+5
Step6: Subtract the number you started  --  (x+5)-x = 5
Step7: write down your answer  -----------  5<br></pre>
