jika 3(4x–1) = 10x + 7, nilai dari 3x–5 adalah

3(4x - 1) = 10x + 7
12x - 3 = 10x + 7
12x - 10x = 7 + 3
2x = 10
x = 5

Nilai dari
3x - 5 = 3(5) - 5
3x - 5 = 15 - 5
3x - 5 = 10

3(4x - 1) = 10x +7

12x - 3 = 10x + 7

12x - 10x = 7 + 3

2x = 10

x = 10/2

x = 5 ✔



Sehingga :

= 3x - 5

= 3(5) - 5

= 15 - 5

= 10✔
