What is the answer to 3/x=-3/3x+5
Aleonysh [2.5K]

Answer:

-\frac{5}{4} =x

Step-by-step explanation:

We first need to bring x up into the numerator. I will find common denominators by multiplying both sides by each denominator.

\frac{x(3x+5)}{1} *\frac{3}{x} =\frac{-3}{3x+5}*\frac{x(3x+5)}{1}

This will eliminate both denominators and leave me with

(3x+5)3=-3(x)\\9x+15=-3x after I simplify the parenthesis.

Now I will solve the equation for x by subtracting 9x from both sides.

9x-9x+15=-3x-9x\\15=-12x

Then divide by the coefficient of x.

\frac{15}{-12}=\frac{-12x}{-12}

-\frac{5}{4} =x
