Question

A.2(3x+2) lebih dari 3(x-4)
b.3(x-2) kurang dari 5x-16

Answer 1

A) 2(3x+2) > 3(x-4)
       6x + 4 > 3x - 12
       6x - 3x > -12 - 4
        3x > -16
         x > -16/3

b) 3(x-2) < 5x - 16
     3x - 6 < 5x - 16
     -2x < -10
       x < -10/-2
       x < 5

Answer 2

A) 2(3x+2)>2(x-4)
=6x+4>2x-8
=6x-2x>-8-4
=4x>-12
=x>-3

b)3(x-2)<5x-16
=3x-6<5x-16
=3x-5x<-16+6
=-2x<-10
=-x<-5 → x<5
