coba bantuin saya, sama masih bingung.. Tolong bantuuuuuan nya

1. 4(x-5) + 5 = 20x
= 4x - 20 + 5 = 20 x
= -20 +5 = 20x - 4x
= -15 = 16x
= -15 -16 = x
= - 31 = x

2. 3x - 5 = 35
= 3x = 35 +5
= 3x = 40
= x = 40/3
= 13.3

3. 4x -20 = 15-2x
= 4x + 2x = 15 +20
= 6x = 35
= x = 35/6
= 5.8

4. 15-2x = x-5
= 15+5 = x+2x
= 20 = 3x
=20/3 = x
= 6.6

5. 4-2(x-1) = 3(x+5)+2
= 4-2x-4 = 3x+15+2
= 4-4-15-2 = 3x+2x
= -17 = 5x
= -17/5 = x
= -3.4


koreksi kalo salah yaa!
