Solve the inequality for x .

x is greater than 5

x>5

Step-by-step explanation:

Basically, pretend the inequality sign is just an equal sign for now and divide both sides by 8 to get x by itself.

You are left with 5<x which should be turned and flipped to x>5 for some weird rule someone made up long time ago.

x is greater than 5 is the final result.

So on your board thingie, get the middle top thing and drag/click so it activated in the answer board. Then put the x in the white box and the 5 in the blue box.

Explanation -:

Given :

Five years ago a man was seven times as old as his son.Five years hence the man would be three times as old as his son

Find :

Their present ages

Solution :

Five years ago a man was seven times as old as his son.

Let us assume

Son's age as 'x'So, man's age as 7x

son's age = (x - 5) years

man's age = (7x - 5) years

After five years

Son's age = (x + 5) years

Man's age = 3(x + 5) years

Now we will calculate son's present age

According to question

3(x + 5) = 7(x - 5) + 10

→ 3x + 15 = 7x - 35 + 10

→ 7x - 3x = -35 + 10 + 15

→ 4x = 40

→ x =

x = 10

Son's present age = 10 years

Calculating man's present age

Putting the value of x = 10 years

3(10 + 5) - 5

→ (30 + 15) - 5

→ 45 - 5

→ 40 years

Man's present age = 40 years

Final Answer :

Man's present age is 40 yearsSon's present age is 10 years.
