I need help with my math please

Question

-3x-(4+5x)=-3/2(8x-6)

Answer 1

-3x - (4+5x) = (-3/2)(8x-6)

-3x -4-5x = -12x +9

4x = 13

x = 13/4

Unless you really meant

-3-4(4+ 5x)= -3/2(8x-6)

-3x -(4+5x) = -3/(16x-12)

-8x-4 = -3/(16x-12)

8x+4 = 3/(16x-12)

(16x-12)(8x+4) = 3

128x^2 -96x+64x -48 = 3

128x^2 -32x -51 = 0

x = 32/256 + or -(1/256)sqr(32^2 +4(128)(51))

=.125+/-.6435

= about .7685 or -5185

but odds are you didn't really mean that

even if technically it's written that way
