Question

Решить уравнение 8:(3*(x+5))=4

Answer 1

8:(3*(x+5))=4
8:(3x+15)=4
8/3x + 8/15 = 4 | * 15*3x
8*15 + 8*3x = 4*15*3x
120 + 24x = 180x
-180x + 24x = -120
-156x = -120
x = -120/-156 = 10/13

Answer 2

8 : (3*(x+5)) = 4
8 : (3x+15) = 4
3x + 15 = 8 : 4
3x + 15 = 2
3x = 2 - 15
3x = -13
x = -13/3
