Math Problem Statement
-2<1-5x≤3
Solution
The given compound inequality is:
Step 1: Solve the first inequality
-
Subtract 1 from both sides:
-
Divide both sides by and reverse the inequality sign (since we are dividing by a negative number):
Step 2: Solve the second inequality
-
Subtract 1 from both sides:
-
Divide both sides by and reverse the inequality sign:
Step 3: Combine the two results
The solution for is the intersection of the two inequalities:
Thus, the final solution is:
