Question

1. 4 - 34 ≤ 10
2. 12 - 6y ≥ - 6
3. 3 ( 2t - 1 ) ≤ 2t + 9
4. 2 ( x - 30 ) < 4 ( x - 2 )
5. 6 - 2 ( y - 3 ) ≤ 3( 2y - 4 )

Answer 1

1). Soal ngk jelas
2). 12-6y ≥ -6
-6y ≥ -18
y ≤ 3
3). 3 (2t-1) ≤ 2t +9
6t-3 ≤ 2t +9
3t ≤ 12
t ≤ 4
4). 2 ( x - 30 ) < 4 ( x - 2 )
2x - 60 < 4x - 8
-2x < 52
x > -23
5). 6 - 2 ( y - 3 ) ≤ 3( 2y - 4 )
6 - 2y+6 ≤ 6y - 12
12-2y ≤ 6y -12
-8y ≤ -24
y ≤ 3
