Jawaban:
a. -2
b. 8
c. 0
d. 2
Penjelasan dengan langkah-langkah:
a. -2(x + 3) = 5x + 8
-2x - 6 = 5x + 8
-2x - 5x = 8 + 6
-7x = 14
x = 14/-7
x = -2
b. 2(x - 5) + 1 = 7
2x - 10 + 1 = 7
2x - 9 = 7
2x = 7 + 9
2x = 16
x = 16/2
x = 8
c. 3(x - 8) = -6(x + 4)
3x - 24 = -6x - 24
3x + 6x = -24 + 24
9x = 0
x = 0/9
x = 0
d. 4(x + 3) = 3(x - 1) + 17
4x + 12 = 3x - 3 + 17
4x + 12 = 3x + 14
4x - 3x = 14 - 12
x = 2
