J’s number is 7.
Explanation of Solution
Given information:
Two inequalities are given:-
and
Calculation:
Solving first inequality
On subtracting variable x on both sides
This gives,
On adding 7 on both sides
On solving,
On dividing both sides by 3
Solving second inequality
On adding 3x on both sides
This gives
On adding 20 on both sides
On simplifying,
On dividing both sides by 2
From first inequality,
From second inequality ,
From both these values of ‘x’ the common value that will satisfy both the inequalities is
Therefore J’s number is 7.
