To solve the system of inequalities, we will solve each inequality separately and then find the intersection of the solutions.1. Solving the first inequality:
Subtract
from both sides:
Subtract 3 from both sides:
Divide both sides by 2:
2. Solving the second inequality:
Add
to both sides:
Subtract 1 from both sides:
Divide both sides by 2:
Now, we need to find the intersection of the solutions for both inequalities. The solution for the first inequality is
, and the solution for the second inequality is
. Since there is no overlap between these two intervals, there is no solution to the system of inequalities.Therefore, the inequality is:
or
Graph: The graph would show two separate regions, one for
and one for
, with no overlapping region.Interval Notation: The interval notation for this system of inequalities is
or
.
