1. penyelesaian dari pertidaksamaan 4 – 5x > – 8 – 3x adalah…..

1. = -5x + 3x > -8 – 4
= -2x > -12
= x > -12/-2
= x > 6

2. = { 3(3x + 2/3) < 5 (2x -2/3) } ×3
= 9x + 2 < 10x – 2
= 9x – 10x < -2 -2
= -x < -4
= x < 4

3. = { 1/2( 2x – 6 ) > 2/3(x – 4) × 6}
= 6x – 6 > 2x – 8
= 6x – 2x > -8 + 6
= 4x > -2
= x > -2 / 4
= x > -2

Itu setau saya.., maaf kalau salah
