Question

gente qual a resposta da equação fracionari seguinte, se puderem monstrem passo a passo
3x/5-1/2=x-2/5

Answer 1

3x/5-1/2=x-2/5

3x/5-1/2=x-2/5
+ 0.6x-1/2=x-2/5
+ 0.6x-0.5=x-2/5
+ 0.6x-0.5=x-0.4
+ 0.6x-1x=-0.4 + 0.5
-0.4x=0.1

We divide both sides of the equation by -0.4 to get x.
x=-0.25
