it would be good to show which angles you are doing


the first line, you are starting with the fact that since ABC is a striaight angle, therefor ABY+YBC=180, so then (x+25)+(2x+50)=180, slving for x, we get x=35 like you did

remember that if AC and DF are parallel, then YBC has the same angle measure as BEF

so find YBC and BEF

we know x=35 so subsitute

2(35)+50=5(35)-55?

70+50=175-55?

120=120?

true


they are paralell
