on5x - 1 < 19
To solve this inequality add 1 to both sides
Now divide both sides by 5
The solutions lie in the area left to the number 4
For the second inequality
Add first we will add the like terms in the left side
Now add 2 for both sides
We need to divide both sides by -1, but we should reverse the sign of inequality
We reversed the sign of inequality when divides it by -ve number
Since 2 < 3
Then if we divide both sides by -1, then it will be
-2 < -3 which is wrong -2 greater than -3, then we should reverse the sign of inequality if we multiply or divide it by a negative number
Then the solutions of the 2nd inequality lie right to -3
Let us draw them
The red part is the solution to the 1st inequality
The blue par is the solution to the 2nd inequality
The area with the 2 colors is the area of the common solution of both inequalities
