Question

(x-5)/10+(1-2x)/5=(3-x)/4​

Answer 1

Resposta:

(x-5)/10+(1-2x)/5=(3-x)/4​

multiplique tudo por 20

20*(x-5)/10+20*(1-2x)/5=20*(3-x)/4

2*(x-5)+4*(1-2x)=5*(3-x)

2x-10+4-8x =15-5x

-10+4-15 =-2x+8x-5x

-21 =x

x= -21

Answer 2

$\mathsf{\dfrac{x-5}{10}+\dfrac{1-2x}{5}=\dfrac{3-x}{4}\times(20)}$

$\mathsf{2(x-5)+4(1-2x)=5(3-x)}\\\mathsf{2x-10+4-8x=15-5x}\\\mathsf{2x-8x+5x=15+10-4}\\\mathsf{-x=21\times(-1)}$

$\huge\boxed{\boxed{\boxed{\mathsf{x=-21}}}}$
