Question

x-3/5=-1/2

Answer 1

\(\dfrac{x-3}{5}=-\dfrac{1}{2}\)

\(\dfrac{x-3}{5}+\dfrac{1}{2}=0\\ =>2.\left(x-3\right)+5=0\\ =>2x-6+5=0\\ =>2x-1=0\\ =>2x=1\\ =>x=\dfrac{1}{2}\)

Answer 2

do bạn ghi đề ko rõ nên mik làm hai trường hợp lun:

\(x-\dfrac{3}{5}=-\dfrac{1}{2}\\ =>x=-\dfrac{1}{2}+\dfrac{3}{5}\\ =>x=\dfrac{1}{10}\\ =>x=0,1\)

Answer 3

= -1/2
