5(3x - 5) = 3(x + 4)
15x - 25 = 3x + 12
15x - 3x = 12 + 25
12 x = 37
x = 37/12
nilai 2x - 5 = 2(37/12) - 5
= 37/6 - 5
= (37-30)/6 = 7/6
3x -5 = 3/5x + 12/5 --------->sederhanakan x 5
15x -25 = 3x + 12
15x -3x = 12+25
12x = 37
x = 37/12
nilai dari
2x -5 = 2(37/12) - 5
= 37/6 - 5
= ( 37 - 30)/6
= 7/6
semoga membantu
