1divided by4 times y + 3=-5x 
:
Assume this is what you mean and you wish to solve for y:
{{{1/(4(y+3)) = -5x}}}
:
Mult eq by 4 and you have:
{{{1/(y+3) = -20x}}}
:
Mult eq by (y+3):
1 = -20x(y + 3)
1 = -20xy - 60x
:
Add 20xy to both sides
20xy + 1 = -60x
:
Subtract 1 from both sides:
20xy = -60x - 1
:
Divide both sides by 20x
y = {{{(-60x -1)/20x}}}
or
y = {{{-((60x +1))/(20x)}}}
