x-1<= 4x+5<6x+7

Solution

x - 1 \leq 4 x + 5 < 6 x + 7

Solution

x > - 1

+1

Interval Notation

(- 1, \infty)

Solution steps

x - 1 \leq 4 x + 5 < 6 x + 7

If

a \leq u < b

then

a \leq u and u < b

x - 1 \leq 4 x + 5 and 4 x + 5 < 6 x + 7

x - 1 \leq 4 x + 5 : x \geq - 2

4 x + 5 < 6 x + 7 : x > - 1

Combine the intervals

x \geq - 2 and x > - 1

Merge Overlapping Intervals

x > - 1
