Answer:

The value of x is 12.

Step-by-step explanation:

To make the denominators the same we can: Multiply the top and bottom of each fraction by the denominator of the other.

$\dfrac{x}{3}-5\cdot\dfrac{3}{3}=-1\\\dfrac{x}{3}-\dfrac{15}{3}=-1\\\dfrac{x-15}{3}=-1\\$

Cross multiply with each other.

$x-15=-1\cdot 3\\x-15=-3\\x=-3+15\\x=12$

What is the answer to this equation using the quadratic formula? 3x^2+2x+4x=0

o-na [289]

$~~~~~~~~~~~~\textit{quadratic formula} \\\\ \stackrel{\stackrel{a}{\downarrow }}{3}x^2\stackrel{\stackrel{b}{\downarrow }}{+2}x\stackrel{\stackrel{c}{\downarrow }}{+4}=0 \qquad \qquad x= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a} \\\\\\ x= \cfrac{ - (2) \pm \sqrt { (2)^2 -4(3)(4)}}{2(3)}\implies x=\cfrac{-2\pm \sqrt{4-48}}{6}$

$x=\cfrac{-2\pm \sqrt{-44}}{6}\implies x=\cfrac{-2\pm \sqrt{(-1)(2^2)(11)}}{6}\implies x=\cfrac{-2\pm 2~i\sqrt{11}}{6} \\\\\\ x=\cfrac{2(-1\pm i\sqrt{11})}{6}\implies x=\cfrac{-1\pm i \sqrt{11}}{3}$

mind you that it has two complex roots, or imaginary values.
