8.2- x< 3(x - 4)
9.7k+3> 4k-2
10.4(3-2y)≤ -12

tolong di jawab yaa ... besk maw d. kumpul

Answer 1

1.x=2
2.p=2
3.
4.x=1
5. t<_-14

Answer 2

1, 13x-3 = 4x +15
    13x-4x = 15 +3
     9x = 18
       x = 2
2. 9p +7 = -11
     9p = -11 - 7
     9p = -18
       p = -2
3. 7 - 3(y-2) = 19
   7 - 3y- +6 = 19
   7+6-19 = 3y
 -6 = 3y
y = 2

4. 2x+1 = -x+4
   2x+x = 4-1
     3x = 3
       x = 1

5.3(x+2)+5 = 2(x+15)
   3x +6+5 = 2x +30
  3x-2x = 30-6-5
   x = 19

6. t-3 ≤ -17
  t ≤ -17+3
 t ≤ -14

7. 3-2x ≥ x+6
     -2x-x ≥ 6-3
     -3x ≥ 3
       x ≥ -1
8. 2-x < 3(x-4)
    2-x < 3x-12
   2+12 < 3x+x
   14  < 4x
     x < 14/4
     x < 7/2

9. 7k +3 > 4k -2
   7k -4k > -2-3
     3k > -5
       k > -5/3
10. 4(3-2y) ≤ -12
     12-8y ≤ -12
       4y ≤ -12
         y ≤ -3
