Question

Please yg pintar bantuin aku tapi pakai caranya yaa pleasee bgt...

Answer 1

1. 6x-3-6+2x=7
8x-9=7
8x=16
x=2

2. -10x+15= 2x-9
-12x=-24
x=2

Answer 2

1. 3(2x-1) - 2(3-x)  = 7
6x -3 -6+2x = 7
8x - 9 =7
8x = 16
x = 2

2. -5(2x-3) = 2x-9
-10x+15 = 2x-9
-10x-2x = -9 - 15
-12x = -24
x = 2

3. 2x -


4. 32≥2(y-3)≥10
32≥ 2y - 6 ≥ 10
32 + 6 ≥ 2y - 6 + 6≥ 10 +6
38 ≥ 2y ≥ 16 (dibagi 2)
19 ≥ y ≥ 8
