Tentukan himpunan penyelesaian dari persamaan 5x + 2(x – 4) = 4(x – 2) – 7(x + 4)

B. -28/10

Penjelasan :
5x + 2(x – 4) = 4(x – 2) – 7(x + 4)
5x + 2x – 8 = 4x – 8 – 7x – 28
7x – 8 = -3x – 36
7x + 3x = -36 + 8
10x = -28
x = -28/10

5x + 2(x – 4) = 4(x – 2) – 7(x + 4)
5x + 2x – 8 = 4x – 8 – 7x – 28
5x + 2x – 4x + 7x = 8 – 8 – 28
10x = -28
x = -28/10
