Question

2<10-4x<6

Answer 1

2>x>1

Answer 2

\[\sqrt[?]{?} nice\]

Answer 3

\[2<10-4x<6 implies 2-10 < -4x < 6-10 implies -8<-4x<-4 implies -2<-x<-1 implies 2 > x > 1 \]

Answer 4

2 < 10 - 4x < 6 --- subtract 10
2 - 10 < 10 - 10 - 4x < 6 - 10
-8 < -4x < - 4 --- divide by -4 and change inequality sign
-8/-4 < -4x/-4 < -4/-4
2 > x > 1
