Tentukan Himpunan penyelesaian dari : 1. 2x-13 = 5x-22 2. 2 ( 5x+4 ) = 6 ( 2x-9 ) 3. 3x-7 = 1/4 -8 4. 1/2 ( 3x-5 ) = 2/3 ( 4x-4 )

1. 2x-13=5x-22
2x-5x=13-22
-3x = -9
x = -9 : -3
x = 3

2. 2(5x+4) = 6(2x-9)
10x +8 = 12x - 54
10x - 12x = -54-8
-2x = -62
x = -62 : -2
x = 31

Maaf hanya nomer 1 & 2 saja yaaa
