BIG POINT TOLONG KERJAKAN SOAL DIATAS DENGAN MENGGUNAKAN CARANYA
Jawaban:
1. a. 6x + 5 = 26 – x
⇔ 6x – x = 26 – 5
⇔ 7x = 21
⇔ x = 21 : 7
⇔ x = 3
b. 2 – 4x = 3
⇔- 4x = 3 – 2
⇔- 4x = 1
⇔x = 1/-4
c. x – 12 = 2x + 36
⇔x – 2x = 36 + 12
⇔ -1x = 48
⇔x = 48/-1
⇔x = -48
d. -5x – 4x + 10 = 1
⇔-5x – 4x = 1 – 10
⇔-9x = -9
⇔ x = -9/-9
⇔ x = 1
e. 2 + x/4 = 5
⇔x/4 = 5 – 2
⇔x/4 = 3
⇔x = 3 • 4
⇔x = 12
