Question
Solve the inequality
k∈(−∞,−1219)∪(47,+∞)
Evaluate
5<3k−41
Simplify
More Steps

Evaluate
3k−41
Rewrite the expression
41(12k−1)
Rewrite the expression
41∣12k−1∣
5<41∣12k−1∣
Swap the sides of the inequality
41∣12k−1∣>5
Rewrite the expression
4∣12k−1∣>5
Multiply both sides
∣12k−1∣>20
Separate the inequality into 2 possible cases
12k−1>2012k−1<−20
Solve the inequality for k
More Steps

Evaluate
12k−1>20
Move the constant to the right side
12k>20+1
Add the numbers
12k>21
Divide both sides
1212k>1221
Divide the numbers
k>1221
Cancel out the common factor 3
k>47
k>4712k−1<−20
Solve the inequality for k
More Steps

Evaluate
12k−1<−20
Move the constant to the right side
12k<−20+1
Add the numbers
12k<−19
Divide both sides
1212k<12−19
Divide the numbers
k<12−19
Use b−a=−ba=−ba to rewrite the fraction
k<−1219
k>47k<−1219
