Mbak tolong jawab nomor tiga ya 1. 2x-4=8 2. 5 (u - 2)=u-2 3. 2x-1=5 4 5,2-7x=0 5. 10=x+6

1) 2x - 4 = 8
2x = 8 + 4
2x = 12
x = 6

2) 5 ( u - 2 ) = u - 2
5u - 10 = u - 2
5u - u = - 2 + 10
4u = 8
u = 2

3) 2x - 1 = 5
2x = 5 + 1
2x = 6
x = 3

4) 5,2 - 7x = 0
- 7x = - 5,2
x = 0,7

5) 10 = x + 6
10 - 6 = x
4 = x

Itu ya jawabannya, semoga membantu
