5).5+3(x-1)=10x-5
Tentukan penyelesaian dari :
Jawaban:
1. 2x + 8 = 17
2x = 17 – 8
2x = 9
x = 9/2
2. 3(x+2)=16
3x + 6 = 16
3x = 16 – 6
3x = 10
x = 10/3
3.2-11x = 38 + x
-11x-x= 38-2
-12x = 36
x = 36/-12
x = -3
4.2t + 21 = 3t-15
2t – 3t = -21 -15
-t = – 36
t = 36
5.5+3x -3 = 10x – 5
3x – 10x = -5-5+3
-7x = -7
x= -7/-7
x = 1
Jawab:
Penjelasan dengan langkah-langkah:
2x = 9 x= 9/2
3x + 6 = 16 3x = 10 x = 10 / 3
2-38 =12x -36= 12x x= -3
21 + 15 = T = 36
5 + 3x -3=10x – 5 7x=2 x= 2/7
