Answer is -4 < x < 1 (Third choice)
Step by step
-26 <4x -10<-6
-26 < 4x - 10 and 4x - 10 < -6
Solve each
-26 < 4x -10
add 10 to both sides to isolate variable
-26 + 10 < 4x -10 + 10
Simplify
-16 < 4x
Divide both sides by 4 to solve for x
-4 < x solution #1
4x - 10 < -6
add 10 to both sides to isolate x
4x - 10 + 10 < -6 + 10
Simplify
4x < 4
Divide both sides by 4 to solve for x
4/4 x < 4/4
Simplify
x < 1 solution #2
Now combine the two solutions
-4 < x and x < 1
Merge overlapping x
-4 < x < 1 is your answer
