Question

What's The Answer?

1/4(20−4a)=6−a

a=?

Answer 1

Step-by-step explanation:

$\huge\underline\red{Answer}$

${\binom{1}{4}}{20-4a}{=6-a}$

$\implies{\binom{20-4a}{4}}{=6-a}$

$\implies{5-4a}{=6-a}$

$\implies{5-6}{=(-a)+4a}$

$\implies{(-1)}{=3a}$

$\implies{3a}{=(-1)}$

$\implies{a=-}{\binom{1}{3}}$
