7 years ago, a man was 7 times as old as his son was. three years hence, he will be three times as old as his son.find the present ages​

Answers

Answer 1

Answer:

Son's age = 14

Father's age = 56

Explanation:

Age of the son = x

Age of the father = 7x

Present ages = x+7 and 7x+7

Future age of the son = x + 14

Father = 7x+14

7x + 14 = 3 (x + 14)

7x + 14 = 3x + 42

4x + 14 = 42

4x = 28

x = 7

7x = 35

x + 7 = 7 + 7 = 14

Son's age = 14

Father's age = 7x + 7 = 7 × 7 + 7 = 56

Answer 2

Answer:

Man: 42 years

Son: 12 years

Explanation:

h-7 = 7(n-7). Eq.1

h+3 = 3(n+3). Eq.2

From Eq. 1

h-7 = 7*n - 7*7

h-7 = 7n-49

h = 7n - 49+7

h = 7n - 42. Eq. 3

Replace Eq. 3 on Eq. 2

(7n - 42) + 3 = 3(n+3)

7n - 39 = 3*n + 3*3

7n - 39 = 3n + 9

7n - 3n = 9 + 39

4n = 48

n = 48/4

n = 12

From Eq. 3

h = 7n - 42

h = 7*12 - 42

h = 84 - 42

h = 42

I begin my free time with a good mind and healthy body fueled with good nutritional foods. Having a good nutritional breakfast helps with energy and mood boost contributing to a healthy and happy mind. I use my happy and healthy mind to unleash any thoughts and ideas onto art, a form of expression. I spend time drawling, coloring, and sketching to come up with a good concept to further develop not only my artistic motive of art but also my skills in art itself. Having different mediums in art has made me a better artist by using what I have around me to make it the best I can to make it mean something. I use cardboard, paper, and canvases to make drawings on different forms with different types of materials such as pencils, markers, oil painting and more which all can turn out differently when used. I also use mediums such as trash, toilet paper, and newspaper to make something creative and unique with unusual materials people usually don’t make art out of. Being involved with Art has helped me further pursue a hobby I enjoy while also helping calm and relax myself mentally as art can be used for self relaxation after days of school.
