Question

Desarrollar la siguiente ecuaciones 2/5x-5/6=5/12 4/7x+15/4=6/5
procedimiento

Answer 1

2/5x - 5/6 = 5/12
2/5x = 5/12 + 5/6   =>  2/5x = 15/12
2*12 = 15*5x
75x = 24
x = 24/75   =>  x = 8/25


4/7x + 15/4 = 6/5
4/7x = 6/5 - 15/4
4/7x = -51/20    =>  4*20 = -51*7x
-357x = 80        => x = 80/-375
x = -16/75
