1. 5x-4 = 2. 15 +2a =9. 3. 3(x-5)-x=-18+5x 4. 4(2x+1)=7x-1 5. 15-2(x+1)=3(5-2) 6. 2 per 3 a -5 = 10 tolong dijawab beserta cara

Jawab =
1) 5x-4 =
5x = 4
x = 4-5
x = -1
2) 15 + 2a = 9
2a = 9-15
2a = -6
a = -6/2
a = -3
3) 3(x-5)-x = -18+5x
3x-15-x = -18+5x
2x-15. = -18+5x
2x-5x. = -18+15
-3x = -3
x = -3/-3
x = 1
4) 4(2x+1) = 7x-1
8x+4 = 7x-1
8x-7x = -1-5
x. = -6
5) 15-2(x+1) = 3(5-2)

15 -2x-2 = 15-6
13-2x = 9
-2x = 9-13
-2x = -4
x = -4/-2
x = 2
