1divided by4 times y + 3=-5x
:
Assume this is what you mean and you wish to solve for y:
1%2F%284%28y%2B3%29%29+=+-5x
:
Mult eq by 4 and you have:
1%2F%28y%2B3%29+=+-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 = %28-60x+-1%29%2F20x
or
y = -%28%2860x+%2B1%29%29%2F%2820x%29
