1. 2(x + 5) - 10 = 2(1 - 5) adalah... 2. -5x -5 = 10x - 5 adalah...

1.
2x + 10 - 10 = 2 - 10
2x = -8
x = -8/-2
x = 4

2.
-5x - 5 = 10x - 5
- 5x - 10x = -5 +5
-15x = 0
x = 0

1. 2(x+5)-10 = 2(1-5)
2x+10-10 = 8
10-10-8 = -2x
-8 = -2x
x = -8/-2
x = 4

2. -5x -5 = 10x-5
-5x-10x = -5+5
-15x = 0
x = 0/15
x = 0

semoga membantu
