Question

halla la solucion en cada caso b)1/5x-7=-3/2x-8 c)x-5/x+6 =4/3 d)6/5=x-7/2(x+1)

Answer 1

1 / 5x - 7 = -3 / 2x - 8
2x - 8 = -3(5x - 7)
2x - 8 = -15x + 21
17x = 29
x = 29/17


x-5 / x+6 = 4/3
3(x-5) = 4(x+6)
3x - 15 = 4x + 24
x = -39


6/5 = x-7 / 2(x+1)
12(x+1) = 5(x-7)
12x + 12 = 5x - 35
7x = -47
x = -47/7
