3x + 5 - 2x + 3 + 2 = 0
3x - 2x + 5 + 3 + 2 = 0
x + 10 = 0
x = -10
jawaban : b. x = -10
pertama tama kita buka kurungnya dulu jadi :
3x + 5 - 2x + 3 = -2
3x -2x = -2 -5 - 3
x = - 10 jawabnnya b
jka tidak percaya silahkan dimasukkan
(3 x (-10) + 5 ) - ( 2 x ( -10) - 3 ) = -2
( -30 + 5 ) - ( -20- 3 ) = -2
-25 - ( -23) = -2
-25 + 23 = -2
-2 = -2 (terbukti kiri kanan sama jawabnnya ) jadi jawab b x = -10
