2/35-2.9x = 0.8x-3/14 ПОМОГИТЕ! 50 баллов

Answer 1

2/35-(29/10)*x = (4/5)*x-3/14
2/35-29/10x = (4/5)*x-3/14
2/35-29/10x = 4/5x-3/14
-29*x/10 = -19/70 + 4*x/5
-37*x/10 = -19/70
x = -19/70 / (-37/10)
Получим ответ: x = 19/259

Answer 2

2/35-2 9/10х=8/10х-3/14
-2 9/10х-8/10х=-3/14-2/35
-2 17/10х=-15/70-4/70
-3 7/10х=-19/70
х=-19/70 ÷(-3 7/10)
х=19/70÷37/10
х=19/70×10/37
х=19/37
