Step 1: Let the certain number be x. According to the problem, when this number is subtracted from 10, the result is 10 - x. Step 2: This result is then multiplied by 2, giving 2(10 - x). Step 3: The final result is 4. So, we set up the equation: 2(10 - x) = 4 Step 4: Distribute the 2 on the left side of the equation: 20 - 2x = 4 Step 5: Rearrange the equation to isolate the term with x. Subtract 4 from both sides and add 2x to both sides: 20 - 4 = 2x 16 = 2x Step 6: Divide both sides by 2 to solve for x: (16)/(2) = x x = 8 The number is 8. The final answer is 8.
