Question

Manuel's age is twice Gupta's age minus 5. The sum of Manuel's age and Gupta's age is 31. Use this information for Items 14 and 15. 14. Let g represent Gupta's age. You can solve the equation 2g - 5+ g = 31 to find g. Which property would not be used in solving this equation? A. Addition Property of Equality B. Commutative Property of Addition C. Division Property of Equality D. Subtraction Property of Equality

Answer 1

2g - 5+ g = 31

3g -5 = 31

3g+5-5=31+5

Addition Property of Equality

3g=36

3g/3 =36/3

Division Property of Equality

g= 12

B. Commutative Property of Addition
