nilai x yang memenuhi persamaan 5(x - 1) - 7 (x - 3)=2(x+3) adalah

Mapel : Matematika
Bab : Sistem Persamaan Linear Satu Variabel

5(x - 1) - 7(x - 3) = 2(x + 3)
5x - 5 - 7x + 21 = 2x + 6
5x - 7x + 21 - 5 = 2x + 6
- 2x + 16 = 2x + 6
16 = 2x + 2x + 6
16 = 4x + 6
16 - 6 = 4x
10 = 4x
4x = 10
x = 10/4
x = 5/2
x = 2,5

Maaf Kalau Salah

5(x - 1) - 7 (x - 3) = 2(x+3)
→ 5x - 5 - 7x + 21 = 2x + 6
→ -2x + 16 = 2x + 6
→ -2x - 2x = 6 - 16
→ -4x = -10
→ x = 10/4

Sederhanakan lg pecahan sehingga
→ x = 5/2
