Pakai cara
Himpunan penyelesaian dari
2(3x + 5) - 2( 7x - 3)= x +7 adalah

Answer 1

2(3x + 5) - 2(7x - 3) = x + 7
6x + 10 - 14x + 6 = x + 7
-8x + 16 = x + 7
-9x = 7 - 16
x = 1

Hp = {1}

Answer 2

2(3x+5) - 2 (7x-3) = x + 7
6x + 10 - 14x + 6 = x + 7
-8x + 16 = x + 7
-8x - x = 7 - 16
-9x = -9
   x = -9/-9
   x = 1
