### High School Mathematics1.11 Applications of Simple Equations

 Example: "Some number added to 7 gives 11," convert this word problem into a symbolic statement. Solution: Let the number be 'x'. If x is added to 7, we get x+7. According to the problem statement, this sum is equal to 11. Therefore, symbolically the statement is x+7 = 11. Directions: Convert the following word problems into symbolic statements. Also write at least 10 examples of your own.
 Q 1: 75 reduced by some number gives 37.x - 75 = 3737 - x = 7575 - x = 37x = 75 - 37 Q 2: 50 reduced by some number gives 45.50 - x = 45x - 50 = 45x = 50 - 4545 - x = 50 Q 3: Some number decreased by 50 gives 35.x + 35 = 50x - 50 = 35x + 50 = 35x = 35 - 50 Q 4: Some number added to 20 gives 11.x = 20 + 11x + 20 = 1120x = 11x + 11 = 20 Q 5: Some number increased by 35 gives 47.35x = 47x = 35 + 47x + 35 = 47x + 47 = 35 Q 6: Some number added to 11 gives 20.11x = 20x + 20 = 11x = 11 + 20x + 11 = 20 Q 7: Some number added to 15 gives 20.x + 15 = 20x + 20 = 1515x = 20x = 15 + 20 Q 8: Twice a number gives 64.2x = 64x = 64*22/x = 64x + 2 = 64 Question 9: This question is available to subscribers only!
