Question
Solve the inequality
x∈(−∞,−3)∪(37,+∞)
Evaluate
x+31>38
Simplify
More Steps

Evaluate
x+31
Rewrite the expression
31(3x+1)
Rewrite the expression
31∣3x+1∣
31∣3x+1∣>38
Rewrite the expression
3∣3x+1∣>38
Multiply both sides
∣3x+1∣>8
Separate the inequality into 2 possible cases
3x+1>83x+1<−8
Solve the inequality for x
More Steps

Evaluate
3x+1>8
Move the constant to the right side
3x>8−1
Subtract the numbers
3x>7
Divide both sides
33x>37
Divide the numbers
x>37
x>373x+1<−8
Solve the inequality for x
More Steps

Evaluate
3x+1<−8
Move the constant to the right side
3x<−8−1
Subtract the numbers
3x<−9
Divide both sides
33x<3−9
Divide the numbers
x<3−9
Divide the numbers
