There are infinite points in the solution set of system of inequalities
and
.
Further explanation:
Given:
The system of inequalities is given as follows:

Calculation:
The set of inequalities are,
…… (1)
…… (2)
Both the inequalities are strict inequalities; therefore they are graphed with dashed lines.
The corresponding equation of inequality (1) can be expressed as follows:
…… (3)
The corresponding equation of inequality (2) can be expressed as follows:
…… (4)
Multiply equation (3) by
as shown below:

Subtract equation (5) from equation (4) as follows:

Simplify equation
to find the value of
as follows:
Substitute
for
in equation (4) to obtain the value of
as follows:
Add
on both sides of above equation as follows:

Now, divide both sides by 2 as follows:
The intersection of the lines
and
is the point
.
Consider test point as
.
Substitute
for
and
for
in inequality (1) as follows:
The point
satisfies the inequality (1) and this point
lies above the line
.
Substitute
for
and
for
in inequality (2) as follows:
The point
satisfies the inequality (2) and this point
lies below the line
.
The graph of the solution set is the shaded region as shown in Figure 1 (attached in the end).
The solution set is the common region for both the regions of inequalities
and
.
There can be infinite number of points in the solution set of both the inequalities.
Therefore, there are infinite points in the solution set of system of the given inequalities.
