Question

Find the value of n: 5} = -4" alt="\frac{10n}{-5} = -4" align="absmiddle" class="latex-formula">

Answer 1

$\bf{Move \ the \ negative \ symbol \ to \ the \ left. }$

$\boldsymbol{\sf{-\dfrac{10n}{5}=-4 \ \ \longmapsto \ \ [Split] }}$

$\boldsymbol{\sf{-2n=-4 }}$

$\bf{Divide \ both \ sides \ by \ -2. }$

$\boldsymbol{\sf{n=\dfrac{-4}{-2} }}$

$\bf{Two \ negatives \ make \ a \ positive. }$

$\boldsymbol{\sf{n=\dfrac{4}{2} \ \ \longmapsto \ \ [Split] }}$

$\blue{\boxed{\boldsymbol{\sf{Answer \ \ \longmapsto \ \underline{n=2}}}}}$

Answer 2

Answer:

n = 2

Step-by-step explanation:

cross multiply

-5 times -4 = 20

10n = 20

n = 2
