Math question5x-5 (6*7x)=65

1 answer:

4 0

$5x-5(6\cdot7x)=65\\\\5x-5(42x)=65\\\\5x-210x=65\\\\-205x=65\qquad\text{divide both sides by (-205)}\\\\x=-\dfrac{65}{205}\\\\x=-\dfrac{65:5}{205:5}\\\\\boxed{x=-\dfrac{13}{41}}$

Find all values of $x$ such that $\dfrac{x}{x+4} = -\dfrac{9}{x+3}$. If you find more than one value, then list your solutions i

mixer [17]

We start with

$\dfrac{x}{x+4} = -\dfrac{9}{x+3}$

Assuming that $x \notin \{-4,\ -3\}$ we can cross multiply the equation:

$x(x+3) = -9(x+4) \iff x^2+3x=-9x-36 \iff x^2+12x+36=0$

You can recognize the perfect square pattern in the quadratic equation:

$x^2+12x+36 = (x)^2 + 2\cdot x \cdot 6 + (6)^2 = (x+6)^2$

So, we have

$x^2+12x+36=0 \iff (x+6)^2 = 0 \iff x+6=0 \iff x=-6$

Which is the only solution, with multiplicity 2.
