3. 4 < 3 x + 1 < 10 =
4. 2 + 2 x < 1 + x =
please mohon bgt di jawab
Tentukaan himpnan penyelesaian dari perasamaan dan ketidakpersamaan
No 1
4 – 3x = 10 – x
– 3x + x = 10 – 4
-2x = 6
x = – 3
No 2
3 – 2x > 7
-2x > 7 – 3
-2x > 4
x < -2
No 3
4 < 3x + 1 < 10
4 – 1 < 3x < 10 – 1
3 < 3x < 9
1 < x < 3
No 4
2 + 2x < 1 + x
2x – x < 1 – 2
x < -1
